We are trying to establish a site-to-site VPN between a Vyatta router and a Checkpoint Firewall. Tunnel comes up successfully.
Also I can reach remote subnet (on Checkpoint ) from Vyatta router.
However , when I ping from remote subnets (on Checkpint) to Vyatta end subnets, it fails. On Vyatta , the vpn logs says;
"peer-<xxxx> -tunnel-4" #2405: cannot respond to IPsec SA request because no connection is known for <xxxx>.
Any idea why Vyatta comes up with the error message.
