Dear colleague,
i've a great problem to solve quickly...
I've to define a lan-to-lan connection with a bri interface over an
isdn channel. I have to use a Cisco 800 with a bri and a ethernet and
a Zyxel LH100.
The config of Cisco is the one below:

------------------------------------------------------------
The zyxel is configured as an lan-to-lan router with a wan address and
a remote peer address corrisponding with Cisco one.
On between routers it's active rip router ver-1.
On zyxel it's set this static rule: 133.133.0.0 255.255.255.0
192.168.40.1

Results: I can open the isdn channel and see the cisco 800 remote
router but i can't ping anymore interface on remote lan. there aren't
any firewalls or other secure policy active on anyone of this two
routers.
Any help will be greatly appreciated.
Thanks,
Paolo
