How to verify ISP has forwarded port?

We have a DSL account. The ISP uses a modem/router combination. They will
not turn off the router portion so we have them forward ports. It doesn't
appear that the ports we need forwarded are forwarded. How do WE test this
for them?

Thanks!
Matt

What exactly are you attemping to do?

Modem/Router combination? Where? on your end of the line?

Phillip,

Yes, modem/router combination.
Yes, on our end of the line.

We need to have OUR VPN (don't ask why, but we do) router on our side
(private side) of the modem/router combination. Then we will user OUR vpn
router to connect to another at a remote site (that site we have no problems
with modem/router combinations)

Basically our ISP is telling us that they have forwarded the vpn service

Then the ISP has nothing to do with the "router portion" or "turing it off".
To get rid of that you yank out the NAT Device (modem/router) and replace it
with a simple "modem only" device,..it has no IP#. Your Server then
requires two NICs and must be setup as a Proxy or a NAT Device. The
"external NIC of the Server connects to the "modem", usually with a
Crossover-Cable. The Server will have the Public IP# on the external nic.
There is even more to this but I can not explain every detail of it here in
a mesage like this.

Then the "forwarding" occurs at your end on the "modem/router" combination.
The ISP simply allows the VPN Tunnel to get there by just not blocking
it,...they aren't "forwarding" anything.

If the Device has the ability (some don't) it is often refered to as VPN
Passthrough. Check the documentation of the Device.
