RE: OT - UDP1000 VPN on PIX 6.3.1

isakmp nat-traversal [<natkeepalive>] will get your UDP working. Just as a
side-note, the older clients that support UDP but do not let you choose to
use it or not will automatically use UDP if the PIX is set for it. That
means if you have not allowed UDP 45000 to you PIX, and you enable
nat-traversal, you will break some users until you allow UDP 45000 or until
you upgrade them to a 4.x client and force non-udp.

I've been using 4.x VPN client for several weeks now, and the best thing for
me is that it no longer removes or conflicts with other VPN clients. Older
versions could not co-exist with Check Point or Windows VPN software, but
4.x does so just fine.

Hello everyone;

Has anyone tinkered with the NAT Transversal VPN on the new PIX 6.3.1
release? It's supposed to be in there (somewhere) but I'll be danged if I
can find explicit documentation on how to enable it.

Have you also noticed that the new VPN client 4.01 is out? It actually
works with the WinXP easy login since it installs a driver vs. a shim into
the OS.
