Ok, if you cant see the SYN/ACK from 10.56.233.99, it could be;
- if the box is multi-homed the SYN/ACK may be being routed out a different interface
- the traffic may be being dropped by iptables (which sits between tcpdump and the OS)

Double check (or maybe post) your iptables configuration.

Also send the output of netstat -ant | grep 198.18.24.3
