Iphone Ipsec vpn to ASA5520 not communicating to local devices
I have an exisitng ASA5520 which is already working with remote clients using Cisco vpn client configured using ipsec over tcp, I am now trying to get vpn access for Iphones working and having a problem where once connected the Iphone cannot ping any internal device. The configuration on the Iphone does not allow for Ipsec over tcp and therefore uses udp 500 by default, if i create a new profile from a pc and do not use ipsec over tcp it has the same issue where it establishes a vpn tunnel but cannot ping any internal device as soon as I change the profile to ipsec over tcp it works fine.
