Yes, I didn't mention it, but I've opened TCP/UDP 5064 and TCP/UDP 5065.

I've opened the port, could connect through telnet, but caget still refuses to communicate. I've tried both the broadcast address and Ubuntu1 specific IP in EPICS_CA_ADDR_LIST.

Failure to connect w/ 'telnet' is good indication of a firewall problem.  However, success only tells you that TCP traffic can get through.  You also need to open up 5064 (and should open 5065) for UDP traffic.
