Cisco Router to VyperVPN Remote Access Setup

Cisco Router to VyperVPN Remote Access Setup

Cisco Router to VyperVPN Remote Access Setup

Hello all,

I am trying to setup a connection from my Cisco 1800 ISR to a VyperVPN remote access connection. I currently have a remote access connection (L2TP Dialer) to StrongVPN, but I want to change my service over to VyperVPN. Everything I have searched on the web is for configuration of home-routers running DD-WRT or Tomato...

Has anyone had any success setting this up? If so, I need some help!



RE: Cisco Router to VyperVPN Remote Access Setup

Config setting are config settings, no matter what you use...they may have different terms to describe each (Like MicroCrap might say "VPN Password", and Cisco calls it "Group", or something like that).

What part are you having trouble with?

RE: Cisco Router to VyperVPN Remote Access Setup

I'm using the current config with StrongVPN with no issues and everything work great. The tunnel is established based on certain types of traffic matching ACL's. All I did was change the setting over to my VyperVPN service info. The tunnel connects when traffic is matched, but drops after a couple of seconds. I am able to pass traffic through the tunnel successfully for those couple of seconds and then it drops. The only way to bring it back up is to reboot the router and then once again, its once up for a few secs.

I've debugged the connection and it looks no different than when I use my StrongVPN service. Only thing I notice is the failed attempts from VPDN when the service tries to connect after the initial successful setup. There is are no errors when the tunnel disconnects.
