VPN QUESTION IS WEIRD

[NightGhos]

I have an small office with a DSL Service and Static IP, i've being having problems with the VPN connection and I noticed that the mask for my Static IP is 255.255.255.255 if i'm recalling correctly i cannot do an VPN IPSec with this type of subnet mask, one location have 255.255.255.248 and the other one have 255.255.255.255 i found that weird, isn't the last 255 wrong? should leave something for the traffic?
Please give me a hint. Here a little drawing:


LOCATION 1 LOCATION 2
IP: x.x.x.x --VPN ---- IP: x.x.x.x
Mask: 255.255.255.248 Mask: 255.255.255.255

That can happen?

Ok, practically i have a Cisco Router behind the Modem (the one that have 255.255.255.255) and i was ICMP the Cisco Router because that is the one that manage the rest of the network.

So I have this:

Cisco ---- DSL Modem ---- IPSec ------ T1 ------ Cisco
x.x.x.x
255.255.255.255

But i cannot figure it out.

so what kind of problems are you having? connecting? staying connected? routing?

The mask is simply a host mask.
