That should be impossible, since the allow TCP 1723 to the WAN IP is
put in by a rule on the back side that you can't edit and is applied
before any subsequent rules.

See the section on "reading raw IPFilter logs" on this page.  
http://m0n0.ch/wall/docbook/troubleshooting-firewall-rules.html
and report back which rule is blocking it, and what that rule is. 
Your entire ruleset might also be helpful.
