Question

Cisco 877W Setup

Asked by: PeteLong

OK Ive got a few of these to set up, they will go in teleworker locations, each one will connect to ADSL, Have a site to Site VPN connection back to the main site (which will have a ASA 5500 Firewall), and each one provide Wireless access at the teleworker site. I am pretty experienced with Cisco PIX/ASA but NOT Cisco Routers.

I'm happy enough setting up the ADSL and the Site to Site VPN with the SDM - Ive had a play with that (Though I did not see anything about Perfect Forward Secrecy - is this enabled on an 800 Series out of the box the same as an ASA?)

But I cant make head nor tail of the wireless settings at all :( sorry but they are not very intuitive, essentially I need to set this thing up to lease addresses to wired and wireless clients, - who both are in the same IP range (and can talk to each other if required) so that all traffic back to the main site is encrypted.

If I set it up as an access point it wont let me using an IP address to the Radio interface thats in VLAN one! If I set it up as a Bridge it sets up with no IP address and I can connect to it -  but I get no IP address (I get a 169.254.x.x) and if I connect two client they cannot ping each other.

Can you please post up your running config with any passwords remarked out.  I personally use an 871w for my home network, and it is a great router for a small network.  I can easily guide you through getting it setup for your DSL (Static or DHCP) and setup the VLAN 1 for wired and wireless access.

We can then verify your vpn access to the remote site.
