Hi all,

I am wondering if I am using VPN to secure the the traffic over public network. And Firewal is in used for protecting the internal network, so is that for those application firewall wall need to looking into the TCP/UDP header to grant access will not able to work? It is because the packets are encrypted in ESP. I know the firewall need to open port for protocol 50, 51 and 500 for IPSEC traffic, but what if some application need the firewall to grant access dynamically?

Or the packet will go through the firewall first and then the freeswan gateway secure the packet just before it leave the private network?

Thanks for any advices.

Calvin
