Hi,

I assume your internal users are part of the x.x.x.x public subnet right ?

First check your routing is working (ping the users from the VPN Server and vice-versa)

If routing is fine (means your 1841 is not the root cause), checks the logs on your VPN server to troubleshoot the IKE negotiation.
