DestIP / SrcIP - Not working?

[shadypalm88]

I'm trying to setup multiple ShoutCast servers on one machine with multiple IP addresses. So I have 2 servers that will be using a PortBase of 8000. When I tried to use a hostname it listened on 255.255.255.255 - obviously not good. Here's what happens when I try to use an IP.

code:
[root@ shoutcast-1-9-2-linux-glibc6]# ./sc_serv > /dev/null &

[1] 4384

[root@ shoutcast-1-9-2-linux-glibc6]# netstat -ap

Active Internet connections (servers and established)

Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name

tcp        0      0 .:8000                  *:*                     LISTEN      4384/sc_serv

tcp        0      0 .:8001                  *:*                     LISTEN      4384/sc_serv

Doesn't look quite right, but when I connect to the IP it's set to listen on it responds, and on any other it doesn't. So far, so good. Taking out the '> /dev/null' reveals that it's not reporting any errors.
But when starting up the other server...

code:
[root@ home]# ukserver/sc_serv ukserver/sc_serv.conf

Damn. Do Src/DestIP not work as I expect them to or is there possibly other chaos at work here?
