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.</P><P></P><P>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.</P><P></P><P>Does the WDS server need to be listed as a DHCP relay server in the FWSM config?</P><P></P><P>Any other possible solutions?</P><P></P><P>Thanks.</P> Mon, 11 Mar 2019 12:20:50 GMT https://community.cisco.com/t5/network-security/pxe-boot-through-fwsm/m-p/1002017#M940556 kschuerman 2019-03-11T12:20:50Z Re: PXE boot through FWSM https://community.cisco.com/t5/network-security/pxe-boot-through-fwsm/m-p/1002018#M940557 <HTML><HEAD></HEAD><BODY><P>You need to enable dhcp relay on FWSM.
