Answered Question

Hello All,


I am having ASA 5510 on my site. I am also having 2 ISP links. the one link i want to use only for Internet surfing & other ISP link i want to use for VPN connection.


Can anyone tell me how to do that ?

Which VPN are you going to use the other ISP link for? It can only be used for static lan-to-lan vpn because you know the ip address hence you can configure static route for the peer address towards your ISP second link.

For remote access vpn or dynamic lan-to-lan, it would not work if the second ISP link is actually connected directly to the ASA, as ASA does not support default route being pointed out off 2 ASA interfaces.

For internet browsing:

route 0.0.0.0 0.0.0.0


For site-to-site VPN:

route <255.255.255.255>

route


Hope that helps.
