Thanks Alex,

I should have looked more closely at the doco :)

Unfortunately your suggestion didn't work: all clients ended up with same 
outgoing IP.

The warning in the logs gives the reason:
2023/07/17 22:19:28| WARNING: Netmasks are deprecated. Please use CIDR masks instead.
2023/07/17 22:19:28| WARNING: IPv4 netmasks are particularly nasty when used to compare IPv6 to IPv4 ranges.
2023/07/17 22:19:28| WARNING: For now we will assume you meant to write /8
2023/07/17 22:19:28| aclIpParseIpData: WARNING: Netmask masks away part of the specified IP in '10.0.0.3/255.0.0.3'

It's treating the mask as a /8.

So back to my problem statement - is there any way to use all four outgoing 
IPs (v4 and v6) with the clients tied to a consistent address?

Thanks,
Scott
