host A                     host B
172.17.2.229      172.17.2.176  202.99.99.99

host A: winnt + exchange
host B: FreeBSD 4.0-release,recompiled kernel and add "options IPFILTER"

I want to redirect outside POP3 requests to Host A via HostB

here is my ipnat config file:

# cat /etc/ipnat.conf

map ep0 172.17.2.0/24 -> 202.99.99.99/32 portmap tcp/udp 10000:65000
rdr ep0 202.99.99.99/32 port 110 -> 172.17.2.229 port 110 tcp/udp

#ipnat -C
#ipnat -f /etc/ipnat.conf

when i try to telnel 202.99.99.99 110,there is no response.

after about 60 second, echo "connection closed by server............."
