Don't know if this will help anybody, but I struggled to find the solution for hours.
My check point secureclient VPN connection worked fine wired into my base netgear router.
However, using a dynex wireless card through the WAP54G didn't work at all. Couldn't google any solution either. Connection to the access point assigned an IP address, but couldn't reach the remote domain to authenticate the session.
Through a stroke of luck, I decided to fiddle with the secureclient settings. First, I cloned the profile for the wireless session. For that profile, under advance profile properties, it had "connectivity enhancements checked", with "use NAT traversal tunneling" and "IKE over TCP". The "Force UDP encapsulation" was not checked. Checking that option allows the remote domain to be reached, and everything seems to work fine now.
Hope this helps someone.
