Connection specific DNS suffix not assigned to VPN clients

Hi,

I have a Cisco PIX 515e firewall and have set up a PPTP VPN connection which works fine, except that the connection specific DNS suffix is not passed on to the client machines when they connect to the VPN and are assigned an IP address.

We are using WinXP clients with the standard MS VPN client software. When I manually enter the DNS suffix into the advanced TCP/IP settings everything works correctly. Any assistance would be appreciated.

DNS suffix is left blank (shown below)

PPP adapter XXXX VPN: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : WAN (PPP/SLIP) Interface Physical Address. . . . . . . . . : 00-53-45-00-00-00 Dhcp Enabled. . . . . . . . . . . : No IP Address. . . . . . . . . . . . : 10.0.4.50 Subnet Mask . . . . . . . . . . . : 255.255.255.255 Default Gateway . . . . . . . . . : DNS Servers . . . . . . . . . . . : 10.0.5.1 10.0.5.2 Primary WINS Server . . . . . . . : 10.0.5.1 Secondary WINS Server . . . . . . : 10.0.5.2
