Dear all,

I am having problems getting DHCP relay working at a remote site

At the Main site i have a Windows 2003 DHCP Server behind a VPN Concentrator 3005

At the remote site i have a Cico PIX 501.

The VPN is workings correctly and can ping from both ends.

Unfortunately no matter what config i put into the Pix i can't get it to relay to the clients.

the config i have tried on the clients is..

dhcprelay server outside

dhcprelay enable inside

dhcprelay setroute inside


dhcprelay server Outside_IP outside

dhcprelay enable inside

dhcprelay setroute inside

and also have included tried both with the following lines in the access lists

access-list inside_nat0_outbound permit ip Outside_IP

access-list outside_cryptomap_10 permit ip Outside_IP

Can anyone help?

Does the VPN tunnel come up? The one that uses the outside_cryptomap_10 access-list.
