SubjectLinux 2.2.17, Advanced routing & a Masq Link
Date
Hi all

I\'ve asked this question on a few other email list with no responce, so as a
last resort I\'m posting it here.

I\'m trying to get a system going which has two links to the internet. One has
class C range routed over it and the other will need to be Masq\'d.
I want to route traffic like smtp, http, https & ftp via the low cost link (the
Masq\'s one)

I\'ve setup Advanced routing based on using 2.2.17 and ipchains & iproute2 (the
lastest as part of debian 2.2r1) using Linux 2.4 Advanced Routing HOWTO as an
example. (there is not a 2.2 how-to for this even thought it is supposed to be
able to do this type of thing) A few of the command did not have a ipchains
equivalent, particularly \'mangle\'.

Using tcpdump I can see the packet come in from my notebook 203.33.246.2 which
hits 203.33.246.1 and is MASQ\'d to the Ipaddress of the isdn link. The
requested information is returned to the ISDN interface but nothing is seen on
the eth1 link going back to notebook.

I also watched the normal ppp link and there was no traffic on this link in
relation to the www connection.

The following is a list of the commands I used:

/sbin/ipchains -A forward -j MASQ -s 203.33.246.0/24 -i ippp+
/sbin/ipchains -A input -i eth1 -p tcp --dport 80 -m 1

root@ppro:~# ip rule ls
0: from all lookup local
32765: from all fwmark 1 lookup lowcost.out
32766: from all lookup main
32767: from all lookup default
root@ppro:~#

ip route add default dev ippp0 table lowcost.out

Any help would be great :)

Cheers & Thanks
Mike O\'Connor
