Has anyone successfully created a VPN tunnel between a Cisco 2600 and Linksys BEFSX41

If so, please share your incredible knowledge. I have a Cisco 2600
Series router and I added VPN accelerator card. We are using NAT
behind the 2600. My WAN guy is going nuts trying to create a VPN
tunnel between the Cisco 2600 and Linksys BEFSX41. We upgraded the
Linksys BEFSX41 to the most recent firmware (1.45.3). Neither Linksys
nor Cisco has been able to help us. If anyone has successfully done
this, your input would be greatly appreciated....

Thanks in advance,
Clem

It isn't easy to find information on this -- lots of false hits.

In the following posting, someone was trying the same thing:

http://www.experts-exchange.com/Security/Firewalls/Q_20743317.html

They gave up and put a Netgear FVL328 in and that worked first time.

 

Lets look at some debugs:

debug cry ipsec
debug cry isa

Might shed some light.

 

In theory as long as both boxes are using the same specs they should
connect.

You may have to experiment a bit. I've found that some VPN routers
although have the same specs some things don't match with other
routers. For instance on an Intel Netstructure VPN router you can't
use the PFS setting against a Nortel Contivity, for some reason they
don't match. I found with some Cisco VPN routers you could not do IP
to IP for the security association. IE: 192.168.1.1 -> 192.168.2.5 (I
had to do subnet to subnet to establish the tunnel properly)

By playing around I was able to get the Intel VPN router to connect
to:
Sonicwall TELE/SOHO
Netgear
Netopia
Linksys BEFVP41/SX41
Watchguard
Smoothwall
Cisco Pix/and broadband VPN's
Nortel Contivity
Netscreen
Synmantec 100R and 200r - Pain in the ass though
Merilus Firecard

If you want send me a snapshot of your LINKSYS log when you're trying
to connect and I may be able to help you out. Blank out your IP info.
I just need the error msg's.

 

Here is how to set up a BEFVP41 to a Cisco 1720, but they should be exactly
the same as what you are trying to do.
