How might I set up a 1720 as a VPN appliance? Also, does the unit need to be in use as a router or can I just use the LAN port and route VPN traffic to it?

THANKS!
 
SDM WILL SET THIS UP FOR YOU. iT IS FREE FROM cISCO.COM, WITH FREE REGISTRATION.

sdm can do it but hitting the command line isn't that hard do a search for cisco easy vpn you can setup all types of vpns and as the name states its Easy :)

Thanks Guys. I'll check these out and advise.
 
The SDM says the 1720 is unsupported, I'll check that thread you posted.
 
Burt - the router won't accept some of the commands in that link.

I give up - I'll just get a VPN3000 on ebay. Thanks for the suggestions.
 
Just popst a sh ver to see what your IOS supports. I wouldn't get a concentrator---don't give up THAT easy. This can be done...

Supported Platforms

•Cisco 1720

•Cisco 1750
Prerequisites

Before you can enable the VPN feature on Cisco 1720 or Cisco 1750 routers, the VPN module must be installed and running one of the following Cisco IOS images with IPSec functionality:

•c1700-sy56i-mz

•c1700-o3sy56i-mz

•c1700-k2sy-mz

•c1700-k2o3sy-mz

•c1700-bno3r2sy56i-mz

•c1700-bk2no3r2sy-mz

•c1700-sv3y56i-mz

•c1700-o3sv3y56i-mz

•c1700-k2sv3y-mz

•c1700-k2o3sv3y-mz

•c1700-bno3r2sv3y56i-mz

•c1700-bk2no3r2sv3y-mz

What commands is it not taking? You should still be able to do a remote access VPN server in that, WITHOUT the VPN Module card in it...

It won't take this:
Code:
cvpn01(config)#crypto isakmp client configuration group xxxxxx
                                                  ^
% Invalid input detected at '^' marker.

cvpn01(config)#
 
cvpn01(config)#crypto isakmp client configuration ?

Post what it says.

Burt
 
Code:
cvpn01(config)#crypto isakmp client configuration ?
  address-pool  Set network address for client

cvpn01(config)#crypto isakmp client configuration
 
3 Users only... I'll begin the dissection... Now where did I leave my antistatic wristband?![bigsmile]
 
OK, so here's one.
I pulled the VPN module, and now I can't log in to the router!
What happened?
 
The router uses AAA.
When I get the login prompt it will take my username, but not my password.
