vpn between sonicwall and cisco asa
Posted on 2011-09-26
I am working on one end of a VPN. This is between 2 different organizations. We run alot of VPNs between differnet organizations, but one in particular seems to have alot of trouble. This one is with a Sonicwall.
It seems that there are times when the sonicwall thinks that the VPN is up and the Cisco doesn't think that it's up. This results in a situation where the Sonicwall can't pass traffic to the cisco. However, if I generate interesting traffic from the cisco end, the VPN comes up and then it works both ways.
So, this is my question:
Are there any "best practice" guides to building IPSEC VPNs between cisco and sonicwall?
Are there any specific features or funtions that don't work between these vendors?
Any other thoughts or recommendations?
