Was wondering if anyone could help me fugure out whats wrong with our 857 router. We wanter to upgrade our network with some vpn options, and chose the 857 router (none wlan). The problem is that we dont get an IP from our ISP. When we talk to the ISP they say that they have connection with the router, but for some reason the ip they send out doesnt stick.
We have the newest ios and the right settings(we think). Logicly, the problem seems to be something with the DHCP client thingy...
When debugging, the ISP and our router is communicating, but nothing more.
How do we continue our troubleshooting? Any ideas what the problem can be? What config should I have regarding the dhcp client protocol?
Solved! Go to Solution.

Hi,
most likely your ISP is using bridged and not routed encapsulation. Please configure:
interface ATM0.1 point-to-point
no ip address
no ip nat outside
no ip virtual-reassembly
bridge-group 1
interface BVI1
ip address dhcp
ip nat outside
bridge irb
bridge 1 route ip
no ip nat inside source list 1 interface ATM0.1 overload
ip nat inside source list 1 interface BVI1 overload

Hi,
PVC 8/35 is down due to OAM failure, beside it never receives anything.
Try:
int atm0.1
pvc 8/35
no oam-pvc manage
If that doesn't resolve, something is wrong with config by ISP side.

Please send router configuration and the technical details from ISP (eg, if PPP is used, VCI/VPI, etc)

Thanks man! That worked just fine, beside from the automatic DNS server update... but we solved that by statictly tell the router about the dns server addresses.
The next item on the "To do List" is to arrange VPN passthrough to our win2k server. If we have any problems in that area we will surely be using this forum again!

Good to know it worked. To automatize dns, configure:
ip domain-lookup
ip dns server
and configure clients (static or dhcp), to use router's inside address as dns.
Thanks for the nice rating, good luck and happy X-mas!

The router is now placed at the correct location and working just fine. next week we plan to configure vpn for remote access.
Instead of making a new post, I though I might as well post it here.
We want to allow access to the local network at the company through VPN. Basicly what we want, is to be able to get access to the local network and it's domain so that a few people can use the recources at work, from a remote location.
We figure this wont be to hard to do. As long ass we get a connection to the local network, our system handles the rest.
12-27-2007 10:53 AM
And the question is ?

My question is:
How do we proceed to configure the router to allow remote access without using the webinterface and software.
