Topology is

Cisco 881 (Outside on the Internet) wanting to create a number of tunnels to Cisco 881's inside a MPLS network. The MPLS provider has provided a Gateway with a Public IP address and they  have created a different IKE and IPSEC port for each inside host that we want to create a tunnel too.

I.e IKE 4510 / IPSEC 45010 redirect inside to inside Host IKE 500 / IPSEC 4500

Can I on my Cisco 881 on the Internet specify the destination ports that happen in Phase 1 and Phase 2?

Running a very basic L2L Config atm between hosts within the MPLS as per Cisco -

 Kind Regards
