[gentoo-server] gentoo router and server on one machine, need help.

[Tamer Higazi]

Hi people!
I am not a network pro, therefor I ask you gladly for help. I have a
gentoo box with 2 eth0 cards. I have red the gentoo home router guide at:

http://www.gentoo.org/doc/en/home-router-howto.xml?style=printable

but I need to use the machine as router as well as server itself.

I have 2 NIC in the machine (eth0,eth1). On the machine is asterisk and
apache installed. I want to use the machine a router and server as well.

the sip gateway connected at eth0 is configured as:
192.168.1.5 with it's gateway 192.168.1.1 and nothing goes along to
asterisk.

I guess, it's not possible to have on the same gateway address a service
running. Could you give me some good advise how to get the thing to run?!

You don't. You have two Ethernet cards maybe.

The main problem here is: Your internet connection is on ppp0, not eth1. 
eth1 makes connection with your modem, so IP communication is not 
direct, rather tunneled (you don't need an IP configuration therefore on 
eth1).

config_eth1=("null")

Also remove the second config_ppp0 line, it overwrites your first one 
which you need ( config_ppp0=("ppp") ). You should get your IP address 
from your ISP even if it's static.

Hi,
I don't really get the question but I'll try to help you out with logic.

Never did I install asterisk but I did build a test case with apache  
and a router on the same box.

First you shall ask what you want to  see on eth0 and eth1. On my test  
case I wanted to see all port of apache on eth1 (lan) and only port80  
on eth0 (wan).

I manage to route all network between lan & wan with simple routing  
rules but I did had to build a special case where I wanted to NAT eth0  
port80 request to my loopback (lo) where my local apache is listening.  
I also NATed eth1 to the lo when explicitly requesting answer from  
eth1's IP (more then 1 IP is handy when using chroot or other special  
security need).

I guess you'll have to setup proper listening port to asterisk before.

Additionally a little bit of reading (more then some howto) could be  
good as securing a router and a server on a same machine is a serious  
task (note that it still a not so hard one) that request a good plan.  
I had to rethink mine twice before getting the good setup. Test  
machine died in a power outage since and didn't got time to build it  
back so I can't supply exemple script.

Hope it did help you out.
