Is the vpn configured to bypass nat ?
Did you add a rule to allow access from vpn to the lan/server?

Have you entered a default gateway into the as400 ? (I believe in as400 its usually referred to as the default route.)

The default gateway should be set to the the internal address of your vpn device.

Its quite likelly not to be configured if the AS400 has not needed internet access.

Yes, that is exactly what would happen if your default route on the as400 was not configured correctly.

Can you show the as400 routing table?

Another thing - does the VPN device accept pings to the inside interface? - if the as400 can't ping it, the route will not get initialised correctly.

You'll have to excuse this question, but I am an AS 400 Dummy.
From where I am now I can access the as 400 through the graphical access program
What command will let me try to ping the router, and how can I see if the gateway is setup on the as 400?

It has next hop set as direct
This should be the router  ip address correct?

to ping it just do:

ping x.x.x.x (where x.x.x.x is the vpn device - probably what your windows machine have their default gateway set to)

on the as400 you need to go (from some kind of shell/command prompt)

go cfgtcp  then select option 2 (work with tcp/ip routes) - what does the *dftroute entry show ?

If you are not comfortable working with the as400, it might be best you ask whoever is responsible for its admin. I know very little about the as400 side - but had exactly this problem with it when setting up a vpn.

and type of service (if it shows) should be standard, not 'mindelay'
