Hello,

Yes you can add another one, yes they both can pass traffic at the same time. The problem comes in if you try to add a default gateway to the new link. That wouldnt work, the ASA can only have 1 default gateway.

You can have this new link for VPN or as a Backup ISP link only.

Just make sure you have a security plus license.

Cheers

Mike

Pls. read this document. You can replace dual ISP with dual MPLS.

There is something called tcp state bypass where we can send one packet of the flow out one interface and receive the response packet for the same flow via another interface.  By doing this you defeat the purpose of the firewall doing what it is supposed to do.  This will make all tcp traffic treated like udp traffic.
