Re: ipsec passthrough on a router

IPSEC Passthrough is a feature of the router that identifies IPSEC traffic and creates port forwards automatically for the PC behind the router

as I know this feature has all Cisco routers so for VPN communication you need permit following protocol/ports ...

protocol esp 50

protocol ah 51

udp port 500 for IKE

udp port 4500 for NAT traversal
