port forward to MS Exchange IMAP

["Christopher L. Everett" <ceverett@ceverett.com>]

All:

I'm trying to open a hole in my firewall so that a 
user can pick up his IMAP email (actually the owner).

I'm trying to use ipmasqadm mfw to do the job like this:

# ipchains -A input -p tcp -y -d 208.145.27.210/32 143 -m 1
# ipchains -A input -p tcp -s 0/0 -d 208.145.27.210/32 143 -j ACCEPT
# ipchains -A input ! -y -p tcp -s 0/0 -d 208.145.27.210/32  -j ACCEPT
<other stuff snipped>
# ipchains -P input DENY

# ipchains -A forward -d 10.0.0.0/24 -s 10.0.0.0/24 -j ACCEPT
# ipchains -A forward -d 208.145.27.208/29 -s 0/0 -j ACCEPT# ipchains -A
forward -d 0/0 -s 10.0.0.0/24 -j MASQ
# ipchains -P forward DENY

# ipchains -P ACCEPT

# ipmasqadm mfw -I -m 1 -r 10.0.0.2 143

When I try to telnet from the outside to port 143 the cursor 
sits there, and I see no reponse.  The IMAP server at 10.0.0.2 
can be reached from the firewall.  NO LOG ENTRIES in
/var/log/messages or any other log I can find.

I'm pretty sure I compiled with the right options set.  At least
I didn't find anything in the IP-Masq HOWTO that had to be set 
that wasn't set.  I haven't found anything in a Google search 
that helps either.

Thanks,

Right now, I'm a bit stuck
