Hello,

I have a little problem on my isdn routers (cisco 800).
I use ISDN links for my WAN backup only. But some routers call in some cases, i precise:
If a computer use a wrong gateway (i saw some computer use their own IP as gateway..., no comment), then the isdn link is up.

My topology.
computer : 10.8.250.x (dhcp range)
router: 10.8.1.250 (and 10.98.8.250)
isdn router: 10.98.8.249 (LAN IP)

i have no ip directed broadcast on my dialer and i don't know what happen and what i can do...

Thanx
