Hi Lewis,

Env Vars are

Host setup
EPICS_CA_ADDR_LIST=Client IP
EPICS_CA_AUTO_ADDR=YES

Client setup
EPICS_CA_ADDR_LIST=Host IP
EPICS_CA_AUTO_ADDR=YES

I don't think the env variables are the cause in this case but I did try looking at the iptables --list and --list-rules after manually running Ralphs script with sudo and wasn't seeing the added rules from the script.  I would think its possible to manually sudo run the script to get them added but I am not that familiar with it.

Those aren't the right environment variables.  You might be abbreviating the names on purpose, but I would recommend you state the exact names you're using so that no one has to guess what you mean, and also just in case you've got a typo in any of them.
