I can only access my vpn when I use a static IP address.  How can I get it to work with a dhcp address given by users ISP?

Is there something I'm missing?  With a static IP it works perfectly.  No problems at all.  When I switch to a dynamic IP it wont connect.  Error 721.

What do you mean by static ip?   for the client or Vpn server ?

the vpn server is a live static IP.  It's the clientside that changes b/c we have laptops that come and go to different places.  But when the laptop goes to a place with a dynamic IP it won't connect.

perhaps it's the ISP provider that the laptop connects to which doesn't allow VPN protocol / or is your firewall only allowing certain ip address ranges to VPN into the firewall ?

i'm sure that's not it b/c we got a static IP and it works now.  So I'm convinced it's server side.
