ASA Client VPN Access using Pre Shared keys

[a.macready]

I have a ASA 5510 that until recently has successfully connected all Cisco VPN clients.

However there is now a group of users who have moved premises and cant gain access. When I switch off the IKE Peer ID Validation, using a Pre Shared Key, it works fine, these users have no problem connecting. As soon as I switch it back on these users in this particular premises fail to connect, are there any firewall settings at the remote site I should be aware of that may cause this issue

ASA has three default tunnel groups, one for each of the following connection types: IPSec remote access, IPSec LAN-to-LAN, and WebVPN. Peer ID validate is the attribute that is not available in external groups. Following link may help you
