It sounds like an ISAKMP problem. Try looking closer at that.

Subject: Nokia M1122 - Server to Server VPN

Hi everyone,

I am not sure if this is a ADSL question or a Server question. I have
searched through the archive and have found a lot a issues with VPN's
over a
M1122 but nothing like the problem I am having.

This is what I have.....

LAN (192.168.111.5) <--> Windows 2000 Server (192.168.109.100) <-->
Nokia
M1122 (192.168.109.254)

I have routed the following ports on the M1122

PPTP-GRE
192.168.109.100
0 0 0

iptype(50)
192.168.109.100
0 0 0

pptp (tcp)
192.168.109.100
1723 1723 0

udp(500)
192.168.109.100
500 500 0

Now what is happening is the server connects to the VPN without any
problems
when I am not using the NAT Routing Protocol in Windows 2000, but
nothing
routes for the VPN traffic. If I enable the NAT on W2k, and add the
demand
dial interface as a public interface, LAN as a private interface and wan
as
a public interface. Add 2 special ports for the WAN interface, udp(500)
and
tcp(1723) to the Nokia's internal IP address. Everything works for about
2
minutes (it is never exactly the same time), then it disconnects and
then
reconnects, it does this 3 times and then won't reconnect for 10
minutes,
and then repeats it over again.

This has me totally lost, so I turn to you all to please help me.

Thanks,
Simon.
