[Solved] Problems with the Home Router Guide

[M4554KK3R]

Hi,
dunno if I'm just too stupid...
I followed the guide (http://www.gentoo.org/doc/en/home-router-howto.xml) exactly, but the

Did you turn on forwarding?

#Enable IP Forwarding
echo "1" > /proc/sys/net/ipv4/ip_forward

Or maybe that doesn't apply to your situation?

yes, i did. even in /etc/sysctl.conf

however, eth1 fails on me on boot, and i dunno why

[M4554KK3R]

some told me to replace the "adsl" with either a "normal" setting like "<ip> <mask> <whatever>" or just don't have any entry for eth0...
however, none of it works so that ppl on my lan can connect (but now i don't get the eth1 error anymore ^^)

[pharaoh]

Yeah if eth1 is your internal nic, give it its own IP and point all your boxes to that IP as their gateway (unless you're running dhcp from your router). Here's my /etc/conf.d/net if it helps:

[M4554KK3R]

my eth0 is the internal link, eth1 the external

right now, my settings are

thanks... however, that didnt fix the problem...

but now it seems iptables does something wrong... the router itself can do whatever it wants on the net while it is totally hidden for others... and users on the lan can't ping outside

[M4554KK3R]

thanks for all your time guys, i finally found the error: it's in the home router guide...

in "Code Listing 5.3: Setting up iptables", in the part with "Finally we add the rules for NAT", the subnetmasks are wrong, they're 255.255.0.0 instead of 255.255.255.0 as used in the rest of the guide (and by me).

I looked over it a dozen times without noticing, but finally i saw it... i was already doubting in myself

I dropped vapier a mail, hope he's gonna fix it

[M4554KK3R]

my fault, my fault...

i didn't read carefully enough about the baselayout > 1.10.foo, i thought it was saying > 1.1.0foo \:
so now the "adsl" part should work according to the mantainer

with the masks i don't know yet, he tells there's no mistake and that they're working for him... not yet a real solution for me, working on it

[pharaoh]

Are your clients set up properly in /etc/conf.d/net? If you're not running dhcp on this router, did you set the clients up correctly?

as i wrote already, everything works fine now, but when i use the three iptables rules with the 255.255.0.0 netmask, noone on my lan can surf the net... however, when is use the same rules with netmask 255.255.255.0 it works fine

according to the mantainer, it should work with both, but since i don't need the former, i'm happy as it is

with baselayout 1.11.11-r3 the line with adsl works fine

[Mgiese]

what did you about the adsl host not found error ? i still cant connect and i do have the same probleml, dhcp works fine, adsl works fine but my client cant ping the internet ... PLZ help me...

I think he's saying that you just need to make sure all your netmasks are 255.255.255.0.

Mgiese: you need a baselayout greater than 1.10 (they're unstable btw, which made me miss them in the first place)

i emerged 1.11.11-r3 which works fine
