Configuring Cisco 871W as VPN-Server

martin.loose · ‎03-02-2006

Hi,

i've just trying to configure an Cisco 871W as VPN-Server for a couple of clients. The Router is placed behind our default gateway and will have a fix ip.

1. are there any sample configs (IOS 12.3(8)Y3) available to tryout and study ?

2. i need a basic configuration to get ssh-access to the router from the internet. At the moment i try to set the wan-interface as public (with the public ip) and vlan1 as private) -> it dowsn't work propperly yet. :( - are there any standards to follow or is this just the way of choice ?

kind regards, martin
