Site to Site VPN with Cisco VPN 3000 Concentrator

[BenChristian]

We have a couple of small sites (3-4 users) that I would like to establish site to site VPN links for using an ADSL connection. Does anyone know of an all in one product (router/4 port switch/adsl modem/vpn endpoint with certificate support)? We are using a Cisco VPN 3000 Concentrator and currently have users connecting to the VPN using the VPN client, however they have been unable to establish more than one tunnel to the same concentrator when using the same ADSL connection.

You could use a Cisco PIX firewall 501/506E or a Cisco 1711/1712 VPN router.

Some NAT/PAT devices have problems with the ESP protocol and they can only handle one IPSec connection at a time. To overcome this issue you may want to enable NAT-T on the VPN 3000 concentrator so the VPN client encapsulates ESP on a UDP packet.

Use the link below as a guideline:

I have used a Cisco 837 ADSL router with a Cisco 3000 and it worked great and has built DSL modem, 4 port switch, IOS, GUI, etc. I used it for VoIP and data on the same DSL link. Reporting is great too.

can the 837 handle a 10-20 users?

Another vote for the 837 in these situations. Will do the job quite happily.
