Hi Tom, After two weeks of nightmares I decided ask You (and anyone reading this mail). Context is as follows: I try to update system on my central router from kernel 2.6.29.6 and Shorewall 4.2.6 (old) to kernel 2.6.31.6 and Shorewall 4.4.4.2 (new). This is LiveCD image boot (Devil-Linux distribution compiled by me), so config is this same. I have established ten OpenVPN tunnels and two

Hi All I am fighting this for 3 days and could not find any reason it is not working the way I want to (or I the way think it should). Internet output interface = eth2 (htb qdisc) Internet input interface = imq0 (eth2 attached - htb qdisc) main class = imq0 1:1 sub1 = 1:ffff (default) sub2 = 1:10 (src ports 1433/tcp or 1434/tcp or 81/tcp or 82/tcp) sub3 = 1:11 (src and dst port 25/tcp )
