This will allow 7 connection.

From and including 1024 upto and including 1030

1024, 1025, 1026, 1027, 1028, 1029, 1030

ALRIGHTY... I set the Local Host back to my external IP, and set the DCC ports to start at 1024(default) and range to 1030. Then I went to my router's port forwarding, and forwarded those ports directly to this computer. And now it works. The only problem there MIGHT be, I'm not sure yet, is that it might limit the number of DCC connections to 6? (1024-1030) But that doesn't matter, I only ever have 1 open, max. I'm yet to test this with DCC'ing someone other than the bot though.

I am not sure about the Linksys router range, but I know on many models of that quality, it allows port forwarding on a slightly betwer details than some.

My router gives me the option to forward up to 10 single ports, and a DMZ (all other ports to one IP). This is isn't the best of configuration, but it is suiting me for now.

Other routers are the same, but allow port ranges, rather than just single port numbers to be forwarded.

A single range of 10 ports, will allow up to 10 concurrent DCC connections (chat, sends, voice, video) at one time. EG, forward ports 15000 to 15009 to your machine. Setup mirc to only use this range for DCC requests (see DCC options).

This may possibly work, however, it may not.

As posted earlier in the thread, not all routers operate correctly, and will drop packets (not allways your won router, it may be the ISP's).

EG, 2 machine on my network 192.168.1.2 and 192.168.1.33.

My public IP is 212.159.100.245 and all ports are forwarded to the 192.168.1.2 machine.

When I want to browse the intranet server on my network, I use my dynamic DNS hostname (coz I can't remember my IP by hart yet).

This works fine while on the internet. However, when on 192.168.1.33, any request for the IP 212.159.100.245 is dropped by eithe rmy own, or my ISP's router.

If it's my own router, then there is nothing I can do, toher than urchase a better router. If it's my ISP's, then it could, but wont be fixed.

It is designed to prevent routing loops. Allthough TTL data will normaly prevent it, it quciker to drop a packet, that was never designed to travel that line in the first place.

Okay I just found this on Linksys site:

Q U E S T I O N

Can I disable the Routers Firewall?

A N S W E R

Unfortunately you can not disable the routers firewall. If you're having trouble accessing servers, or running servers on your network you will need to find out what ports the programs are using. Once you've done that you'll need to setup Port Forwarding (KB10933123) or Port Triggering (KB10934316). Port Forwarding is used for setting up servers behind your router that you want the outside world to access and Port Triggering is used for servers outside of the routers which you want to access.

Hmmm... That makes things difficult because irc and eggdrop use a million different ports, they almost never use the same one twice, well, they use what is available or something. Such as DCC port range is 1024-5000, that is a lot of ports. Although, I can change this, so could I maybe set this to like 1024 to 1025 and forward those?

Okay DCC works now if I set my ip as my internal ip. Now that ruins it for DCC'ing to anyone else.. lol.. Kind of a lose-lose situation. Would the routers firewall be the reason why I can't DCC when my external ip is set in that box? Because if so, I might be able to disable the hardware firewall and just use Zone Alarm or something. I know the router has a thing called Port Triggering, but I haven't quite figured it out. I can't just forward all the ports because that would interfere with the other PC on the network.

Then as noted in my previous posts, change this IP to your internal IP, and you should be able to DCC CHAT the bot, though it will break, if you try to DCC CHAT any1 else.

It is because of the external IP address, being in this box, that it doesn't work.

My ip in mirc's options, is set to my external ip. Then there is local host above that I think it is, and it is my hostmask.

This realy does sound like a clash between your network setup, and the mirc client.

Have you tried changing the IP your client thinks youa re before using DCC CHAT?

mIRC gets very confused, and uses the wrong IP, which will cuase eggdrop to fail to DCC CHAT to you.

Okay well I tried many things in the conf file, including setting my-ip, nat-ip, and finding the ports (2010-2020), but they are for file transfers which may be different. But anyways, when I set these things up, I couldn't even CTCP. So I got it back to normal now, and CTCP works, but still no DCC. BUT, it doesn't matter really, CTCP'ing to the bot to initialize the DCC is just as easy as DCC'ing in the first place. lol. So it's not really any loss that I can't DCC, as my router's firewall isn't blocking any information. For the seldom amount of times I actually log into my bot, I can definately live with the CTCP and mIRC's Process ANSI Codes.
Thanks for the help ppslim and Photon.

number one : You can only set my-ip and nat-ip in the conf file - but I think you already realised that.

The ports that eggdrop uses are mainly the one that you set for listen (bot/user/all) in the conf file. These are certainly the only ones used for two way communication. Uptime.mod communicates out (only) on port 9969 (UDP) but I guess you are forwarding all traffic out.

Setting my-ip and nat-ip don't seem to work. This is what happens:

[18:30] .set nat-ip **.***.***.***
[18:30] What? You need '.help'

I'll look through the .conf file, since I'm sure you can set it there.
Thanks for all the help, I really appreciate it.
*Also, do you know what Port(s) Eggdrop uses? This way I can forward them to my pc.

OK, this setup is not that complex, but can be confusing on settings.

The following should be noted for your eggdrop config settings.

nat-ip should be set to your static external IP (that seen on the internet and IRC).

my-ip should be set to the internal IP.

Seeing as your machine is assigned a dynamic IP from the DHCP server within the router, I would recomend changing it to a static IP. It will save you having to change your eggdrop config each time the IP changes.

This is no more of a security risk, than it presently is.

Weather or not the normal DCC CHAT method works, is based on how your router, and your ISP's router operatesm, and your IRC client.

99% of routers (your average joe cable router, more complex 3com or cisco routers will allow this) will not allow for this to operate correctly.

It will also depend on your IRC client.

If, like mIRC, you can change the host/ip your client thinks you are on, then you can quickly fix it.

CHange this value to your internal IP, and DCC chat will work.

If you can't do this, then it's up to the routers.

When you send a DCC request, the IP/host of your external IP is sent to the bot. The bot will try connecting to this port.

When the bot tries to connect to this, the router will either either kill the packets, forward them to your ISP, or route them within your network.

On top of this, it will depend on your port forwarding options.

99.9% of the time, it will not work in a Internal LAN, because of the complexity of the routing system.

I'm running on a Cable internet connection with a static ip. Between my pc and the modem there is a Linksys 4 Port Router. The bot is run off of the same pc that I use every day, such as it is used to connect to IRC and to DCC to the bot. So, I assume that wherever I tell the bot my IP, I could just set it as localhost? If not, would it have to be my Internal/LAN IP designated by the router, or the External/WAN IP designated by my ISP? And where do I set this at?
Thanks

This has been reported before, but isn't reproducable by many of the developers, so it may be a while before you only have to use it once.

The mIRC option is to process the incoming codes, and turn them into mIRC coliur, bold and other codes, or to simply ignore them (if not supported).

So yes, you can use this, and it won't harm you.

As for not being able to DC chat the bot, this could be many things.

First off, make sure you are using the correct value for my-ip.

Second, make sure you should be using my-ip, and not a combination of my-ip and nat-ip.

If you give a discription of how the system is connected to the inernet, we may be able to help more.

Okay thanks. I still haven't figured out why I just can't DCC in the first place. I read some topics but they generally didn't ahve a fix. And what is the difference between using the .fixcodes and just setting mIRC to "Process ANSI Codes"? Would it be the same just to tick Process ANSI Codes instead of typing .fixcodes everytime? Also, I just noticed with .fixcodes you have to do it twice. The 1st time says

[04:30] #Stylez_Kc# fixcodes (telnet on)

and I still get the garbled stuff, then I do it again and I get

[04:30] #Stylez_Kc# fixcodes (telnet off)

and then it works fine.
