Jim,
What we need here is the ability to masquerade the encrypted payload. The kernel that
STN is compiled with is 2.0.33, 2.0.37 had the patches in.
Basically, you need this facility if you are using a PIX or Firewall1 as your Internet
access point. The UDP (Port 500) packets are sent OK. However, masquerade works by
changing the source address form your private range to IP address given to you by your
ISP. This is the problem, if the source address is changed the checksum fails so the
firewall rejects the packet.
If you go to Google and search for IPSEC masquerade it has a much better description
than I can give.
PPTP is a TCP protocol that can survive masquerade with the current STN version
Ian.

I am a little confused here.....
Ian (and others) are clambering for IPSEC masq, (and I'll vote for that
too. . . but...)
1. Will someone please remind me what it -IS-??
2. Stan is making noises like this means STN does not support outbound
(from home to work via STN) VPN...... it either does not work - or does
not masq properly???
The version of STN -I- have, does, repeat DOES support outbound VPN. (I
think, but am not sure, that it does not support -INBOUND- VPN)
I have a work laptop that I can plug into the network at my job, and due
to the way I have DNS configured on my "home" network - I can plug it in
here, and it can find the gateway, etc. just fine. In fact, I often use
my home network, and associated cable connection thru STN, to make
outbound VPN connects to my job. I connect thru to the network -
download test files, start servers and services, and otherwise go hog
wild. No problem....
Maybe I am missing something??
