No DHCP Addresses for VPN Clients - 3.Oct.2004 9:41:00 PM

Hi,

I have configured everything for PPTP VPN connection, but when I connect to the ISA server I am getting an APIPA (169.254.x.x) address, because my DHCP is not working for VPN clients.

I have configured a scope which should be used, but it doesn't seem to use it.

When my VPN connection has been setup from the client and watch the details of the connection it shows a 169.254.x.x address for the client, but also for the server.
I don't understand why, because the server has two nic's with static addresses.

Anyone knows why it shows a 169.254 address for the server ? and how can I resolve this ?

thanks

Hi PM,

Where's the ISA firewall?

Where's the DHCP server?

Thanks!
Tom

Hi,

sorry I wasn't very clear,

ISA and DHCP are all running on the same system.

Hi Tom,

I have the same problem as PM. I run ISA2004 on a domain member server as an edge firewall and my DHCP runs on the another member server in my domain.
I configured DHCP Relay Agent on my ISA2004 server LAN interface but I can not solve the problem.

If you change things for ISA VPN that affect to RRAS, like the number of PPTP or L2TP connections, perform the following to force RRAS to find the changes. This also applies to changes in DCHP if your have configured RRAS for DHCP Relay.

1> Click Start, point to Programs, point to Administrative Tools and click on Routing and Remote Access.
2> In the Routing and Remote Access console, right click on the server name in the left pane of the console. Point to All Tasks and click on Restart.

This will cause the RRAS server to obtain IP addresses and refresh the DCHP leases.
