TAL-IPC protocol with pf

[Brandon Mercer <b.mercer@trustetc.com>]

Hello Group,
Boy have I got one for you!  So my broker dealer upgrades his software 
that he uses to get pricing and he can't get any information.  I'm on 
the phone with their tech support and she says that I need to allow port 
1838 outbound on my firewall.  Fair enough, I try that and things still 
don't work.  So I verify with the tech support rep that it runs over 
tcp... **BIG PAUSE** she replies, well actually it works over TAL-IPC 
which is a proprietary protocol that we've developed.  Oh... ok... so 
tcp wasn't good enough for you?  Anyway, the problem as it stands is 
that I still need to make this work.  I'm running OpenBSD 3.5 and here 
is a snippet of my ruleset. 

outgoing = "{ 20, 21, 22, 25, 80, 110, 443, 10000, 21001, 22001, 1838 }"

pass in quick on $external inet proto tcp from any to any port $outgoing \
     flags S/SA keep state
pass out quick on $external inet proto tcp from any to any port $outgoing \
     flags S/SA keep state

pass out quick on $external inet proto udp  all keep state
pass out quick on $external inet proto icmp from any to any keep state

Thanks for any help,
Brandon
