iPaq 3630 and Gentoo internet

Spherical · 12-04-2006, 06:42 PM

Yes, I know, a lot has been posted about this already, but not about how to get internet to work on an iPaq that is connected through serial (Com something, ttyS0)

So, all works, I can ping to my desktop, and to my iPaq, but the internet is not working, and I'm puzzled, since according to my routing table it should work.

Anyone have any idea?

My routing table:

Code:

Thirza          *               255.255.255.255 UH    0      0        0 ppp0
192.168.100.0   *               255.255.255.0   U     0      0        0 eth0
loopback        *               255.0.0.0       U     0      0        0 lo
default         192.168.100.2   0.0.0.0         UG    0      0        0 eth0

Ow, Thirza is my PDA/iPaq device thingy, connected on ppp0 as 192.168.100.110

hello,

what are the forwarding rules you set up ???

Nevermind, thanks for pointing it out!

got it figured...

Code:

iptables -F
iptables -t nat -F
iptables -t nat -A POSTROUTING -s 192.168.0.2 -j MASQUERADE
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -A FORWARD -s 192.168.10.11 -j ACCEPT
iptables -A FORWARD -d 192.168.10.11 -j ACCEPT

This was how I had set it up, the forwarding... spot the error please!

Anyway, thanks again for pointing out the forwarding rules!

here are the rules I would use:

Code:

echo 1 > /proc/sys/net/ipv4/ip_forward
        iptables -A FORWARD -i eth0 -j ACCEPT
        iptables -A FORWARD -o eth0 -j ACCEPT
        iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE

Also I would choose another network address for ppp0. As a matter of fact ppp0 IP address belongs to the same network than eth0 address. For example set ppp0 address as 192.168.101.1

Regards,

Ehm, no, the eth0 (LAN) address here is in the 182.168.100.* range

But i gotta say, your solution is cleaner and more better to work with. Thanks!
