Please note,

Sometime last month (since Sept-19 I believe, according to one report), UCIS changed the VPN server configuration such that rules in the POLAN router/gateway were no longer correct.

The net result was that the desired behaviour (previously in place) of allowing "Dal VPN clients to SSH to ANY system in POLAN" was no longer effective.

The configuration has been updated effective ~4:45pm Tuesday Oct.9th and now things appear to be working correctly, ie, Dal VPN clients can access SSH services on any system inside POLAN.

(In contrast, non-VPN clients "on the internet at large" are restricted to a limited number of "gateway servers" - the most common of which is anchor).
