[FW1] Encapsulated UDP,Hiding NAT, Cable access madness



The story so far:

I have a network protected by 3 Nokia/VPN-1 4.1 SP2 firewalls and I've setup
SecuRemote access.  Dialing up and using SR works with no problem.  I then
setup a Linux box with basic IP MASQ and dialup.  Same laptop works behind
this hiding NAT device (UDP encapsulation varified in packet capture).  So
far, so good.  Home I go to my trusty ATT Broadband cable connection.  No
go.  Packet capture shows informational packet "NO-PROPOSAL-CHOSEN".  SR
tells me user is not configured properly.  I unload ipchains rules and
reload with very basic IP MASQ support (same as dialup test).  Nada.  Tried
adding ":force_udp_encapsulation (true)".  Nope.

Ideas?

Bradley
