Kind of an oddball question, sorry!
I have two NICs. One's for general use, plugs into a router, standard stuff - Aussie IP address. The other one is for an encrypted VPN, with very little use (non-aussie IP). Gateway and other metrics are set so that windows and all it's apps should always use the 'general use' NIC - as it always has the lower metric in all cases.
(VPN NIC connects to a dedicated 2ndary router which deals with the VPN login etc, different local IP subnets, no DHCP - static IPs).
Works like a charm, until -apparently at random, not always - i find my browser (and i'm assuming all other standard apps on windows) accessing internet through the VPN/2ndary NIC.
I have not observed the issue without having run ESO, and have therefore ruled out problems with networking metrics. IPv6 is turned off. Distinct and manually assigned gateways + metrics +IPs seem to rule out anything but ESO.
THis is almost always coupled with a prompt about "this computer not authorised", and/or login difficulties "requesting login' issue (which is fixed btw, if i disable then enable the VPN NIC after closing ESO client).
Theory: ESO.EXE likes an IP address closer to it's American servers. Sometimes. I'd appreciate opinions and thoughts. Also strong pain killers.
