We are looking at replacing our existing internet facing Watchguard firewalls with Cisco ASA. The Watchguard currently has a number of sit to site VPNs with variously branded 3rd party firewalls.
These will need to be maintained. Is the ASA compatible with all other branded firewalls (Nokia, Juniper etc) in terms of VPN connectivity?
Many thanks for any answers
Sure it is! VPN is not something proprieatary to an X brand, it is a standard that all vendors have to work correctly.
Dont forget to check the IOS bundle if it supports the amount of VPNs you like.
