[Sidewinder] SYN/ACK issue

[Sidewinder moderated discussion list]

All,

            We are in the process of implementing a G2 firewall and trying
to figure out Proxy/IP Filter rule sets.  We have most of it complete but
are having an issue with one of the rules.  We are trying to create an IP
Filter rule that allows access from the internal burb to the external burb
on tcp port 6667.  This would seem to be a straight forward rule with no
complication.  However, when we implement this rule the logs explode with
entries saying "Expected SYN, Got ACK" - Once this rule is implemented
everyone is dumped off the IRC server even though there is another IP filter
rule that we placed below that one which allows for all TCP ports.  I've
tried researching this over the net and can't find anything.  I would open
up a case but figured I'd post here first to see if anyone may have
experienced this before in the past or is a relative easy fix that maybe
I've overlooked.  

 

Thanks,
