Hello. I have an 6500 VPN SPA Adapter. I run a site-to-site, digital certificate authentication scenario.

I have 2 Vlans in my crypto engine, one with a remote-access crypto map, the other with a site-to-site crypto map. I am only using now the site-to-site crypto map.

The IPsec negotiation completes successfully. Still, the traffic between ESN and PSN is not working.

My topology:

ESN( - security gateway ( ---- ( - ipsec interface) cisco spa vpn adapter ( - clear ip interface) --- PSN(
