It's been a while since I had to debug my firewall setup but here are a few
tips:
1. Do you have ip_forwarding (in /proc/net....) enabled?
2. Are you binding 2 IPs to a single card? If so, is it still doing it
since upgrading?
3. Zero the counters ('ipchains -Z') and then attempt a connect on 98 box
and check the counters ('ipchains -L input -v') again. Repeat for 'output'
and 'masq' (or is it called 'forward') chains.
That should narrow down the list of possible problems.
