PXE boot through FWSM

I am attempting to setup a windows deployment server to work through our FWSM. The workstation and DHCP servers are on different vlans on the outside interface of the FWSM. The WDS is a separate vlan on a different FWSM interface. The workstation is getting an IP and I verified that it is receiving option 66 and 67 using wireshark.


The client will get an IP address at boot, but I receive a TFTP open timeout error. I do not see any deny messages in the FWSM log viewer. I do have an ACL allowing TFTP to the WDS from any.


Does the WDS server need to be listed as a DHCP relay server in the FWSM config?


Any other possible solutions?


Thanks.

You need to enable dhcp relay on FWSM. In order to enable DHCP relay on the interface connected to the clients, enter these commands:

dhcprelay enable Outside

dhcprelay server ip_address Outside
