Services -> loadbalancer for smtp issues

[dullyouth]

First off, i'm running pfsense 2.0-rc1

WAN (wan)                -> bge0      -> xxx.xxx.83.252
  LAN (lan)                -> bge1      -> NONE
  OPT1 (opt1)              -> em0        -> 10.0.0.200 (crossover to secondary fw)

I'm running pfsense inline(i think that's the right term) and was wondering if it were possible to set up a load balancer between 83.252 and other ips on the same 83.0/24 subnet when only assigning an address to the wan.

The network has 7 class C's in total, and no "internal lan" as they are all accessable via the net, pfsense is mostly used in conjunction with snort as an IDS(recently upgraded from obsd 4.1) but i'd like to use it for load balancing our mail servers as well.

I'm getting TCP SYN_CLOSED when i attempt to connect to the loadbalancer listener

results of pfctl -s state
all tcp xxx.xxx.83.181:25 <- xxx.xxx.83.252:25 <- OFF-NETWORK-IP:34112      CLOSED:SYN_SENT
all tcp OFF-NETWORK-IP:34112 -> xxx.xxx.83.181:25      SYN_SENT:CLOSED

83.181 is the smtp server.
OFF-NETWORK-IP is a remote server connecting to wanip/load balancer listener

relayd.log
Feb 15 11:12:40 fw05 relayd[2593]: host xxx.xxx.83.181, check icmp (0ms), state unknown -> up, availability 100.00%
Feb 15 11:12:50 fw05 relayd[2454]: table smtp: 1 added, 0 deleted, 0 changed, 0 killed

relayd.conf
log updates
table <smtp>{ xxx.xxx.83.181 retry 2 }
redirect "smtp" {
  listen on xxx.xxx.83.252 port 25
  forward to <smtp>port 25 check icmp timeout 1000
}

I may be completely off base here as i'm primarily the solaris/nix admin and web developer, my network-fu is somewhat minimal.
Any information, or a blatant "you have no clue what you're doing/it will not work" would be greatly appreciated.</smtp></smtp>
