DHCP relay not forwarding DHCPOFFER packets to clients

Headline pretty much says it all. I've a load-balanced config with DSL and Comcrap, plus a host of internal VLAN's, so my config is a little thick.

 

Stay focused on VLAN 60, though, because that's the VLAN having trouble right now. Specifically, I've used Wireshark to packet capture on both my DHCP client and DHCP server.

 

I can clearly see the server receiving two DHCPDISCOVER packets from the EdgeRouter (yay, dhcp-relay!). I can also see the DHCPOFFER packet leaving the server in Wireshark.

Unfortunately, my client never receives the DHCPOFFER packet. I have tried three different clients.

I have no idea what the issue could be and would love for someone to tell me I'm being an idiot and that there's an easy solution to this! Image may be NSFW.
