hAP AC (962UiGS-5HacT2HnT) ROS v6.46.4.
- ISP_1 (2 dynamic IP, 500 Mbps),
- ISP_2 (1 static IP, 100 Mbps),
- 2 masquerade, srcnat rules, Out Interfaces ISP_1, ISP_2,
- 10 rules for internal servers forwarded from ISP_2,
- default RouterOS rules
my configuration was worked fine for 5 years, but one ISP_1 (2 dynamic IP, 500 Mbps) do some nightly service works, "broke my internet connection", router switched to ISP_2 (1 static IP, 100 Mbps), I call service and get technician visit, tell him history, he calls some master technician, he reconfigure something at their site, and ISP_1 internet works, if I directly connect computer to it
but!
if I connect this ISP_1 Ethernet cable to router, router switches to WAN1 - ISP_1, but ISP_2 link stops working - PING stops, internal services from outside are not accessible, if I disable ether1_ISP1, all starts working again after second
it looks like, that when ether1_ISP1 is enabled, all data goes somewhere wrong, but I can't find where and why
