I believe rule 1 as above should be
	ipchains -A input -d 0/0 5200 -p TCP -j ACCEPT
(you don't want to just accept the SYN flag'ed only packets, you want to
accept all inbound to tcp port 5200)

What about TCP port 5200? Don't you need to forward those as well, to
your Echolink software on your Windows98 machine?

I take you are using something like tcpdump,
 tcpdump -i eth0  udp dst port 5198 or 5199


I hope this is some help, good luck.
