I am making my gentoo PC as a router.
I was reading the official guide.
The wan connection is a usb modem connecting through ppp.
How do i fit it in the guide?

No its not adsl its a 3G wireless evdo modem something like a cellphone modem.
I have to issue several init commands before connecting.
I normally use kppp or wvdial to connect |

The tutorial talks about setting up the internet connection using the modem.
I have already done that.
I want to route the connection to other pcs and i can't understand how to fit this type of connection in the wan part of the official tutorial.
It talks about using eth1 as the adsl port but mine is a usb modem dialled using kppp or wvdial. |

Well, is exactly the same, just replace any occurrence of eth1 by your WAN device name.
You can get the device name by simply running ifconfig.
As said in the official guide:
| Quote: | Copy and paste these examples ...
# export LAN=eth0
# export WAN=#here goes the device name, ppp0 or whatever |
Cheers!

shaumux,
Use the name ppp0 where the guide says to use eth0 or eth1 ... whichever interface is connected to the internet.

Thanks for the help.
The router setup is working as i want it to.
Now is there some way to implement upnp for dynamic port forwarding but only for a specific system?
Also can i use nat based on mac address and not on ip address as i want to give net access to specific system. |

You can filter any kind of traffic by mac address issuing for example:
| Code: | | iptables -A INPUT -m mac --mac-source 00:11:22:33:44:55 -j DROP |
Im interested in upnp automagically port forwarding too. Let's see if someone else can give us a clue.
Cheers!

can i do?
| Code: | | iptables -A INPUT -m mac --mac-source 00:11:22:33:44:55 -j ACCEPT |
Will it override the ip based rules? |

Hi againg, iptables list of directives is parsed sequentially, so any rule ending with -j ACCEPT will override any denying rule parsed after that one. No matter if is mac based or ip based.
Cheers!
