Help on RRAS

Hi all,

I have two LAN's to be managed.
I have (in the first LAN, assuming as LAN 1) a Win2003 server acting as
a router, using RRAS. I have two NIC on it, one direct to the internal
LAN, the second connected to a firewall (and from this to the internet)
installed and managed by my ISP.

The NIC A (internal LAN) has 192.168.250.101, no default gw.
The NIC B (internet) has 192.168.250.240, default gw: 192.168.250.241
(the firewall).
The firewall has 192.168.250.241
Clients are 192.168.250.x, default gw: 192.168.250.101
The NIC A is connected to a switch, together with the rest of LAN.
The NIC B and the firewall are connected to a second switch.
Clients are currently going in internet, no problems.

This is the configuration in the remote LAN (LAN 2):

The firewall, also installed and managed by my ISP, has
192.168.251.245.
Clients are 192.168.251.x default gw: 192.168.251.245.
No server acting as a router here; easier situation.
Clients here also use internet, no problems.

Well, I can connect from LAN 1 (the first one described above) to LAN
2, I can ping all IP's, use remote desktop etc.
But users working in LAN 2 can just ping the firewall (192.168.250.241)
and the NIC B (192.168.250.240) in the LAN 1, the devices that are on
the same switch.

I have configured RRAS as default wizard, using NAT as option; IP
routing is enabled. It works fine, because clients on LAN 1 can go to
internet and ping LAN 2.
I cannot understand why LAN 2 clients can't see LAN 1...

Any help would be appreciated.
Thanks.
Max
