I tried this but no luck.

I find that every second connect works, eg..
[midget 20:12] ~ >sudo pfctl -s state | grep 203.31.81.10
No ALTQ support in kernel
ALTQ related functions disabled
all tcp 203.31.81.10:22 <- 10.0.2.99:55188       ESTABLISHED:ESTABLISHED
all tcp 10.0.2.99:55188 -> 121.45.249.156:55188 -> 203.31.81.10:22       ESTABLISHED:ESTABLISHED
all tcp 203.31.81.10:22 <- 10.0.2.99:55190       CLOSED:SYN_SENT
all tcp 10.0.2.99:55190 -> 121.45.57.17:55190 -> 203.31.81.10:22       SYN_SENT:CLOSED
all tcp 203.31.81.10:22 <- 10.0.2.99:55194       FIN_WAIT_2:FIN_WAIT_2
all tcp 10.0.2.99:55194 -> 121.45.249.156:55194 -> 203.31.81.10:22       FIN_WAIT_2:FIN_WAIT_2

As you can see it mentions the old (121.45.57.17) and new (121.45.249.156)
IPs..

I have no idea where it is getting that IP from.. ifconfig & netstat don't 
show it.

I've even tried /etc/rc.d/pf restart but that doesn't fix it.. It's very 
perplexing :(
