Two providers, three links
-
Good afternoon friends!
I need your advice again.
The situation is as follows. There is Pfsense version 2.5.0. He receives 3 links from two providers. IP addresses are from different subnets and do not overlap with each other. Provider # 1 and provider # 2 have been working with each other for a long time and adequately, but as soon as I turn on the interface with link # 2 from provider # 1, problems begin. After about an hour, both links from provider # 1 are disconnected and cannot reach their gateways. Some kind of routing problem, apparently I can't figure out where (
The loop?
I tried to make a rule on the firewall prohibiting walking from problem subnets to each other, but it did not help.
Where to look?

Are link 1 and 2 sharing the same ISP gateway IP ?

Check https://docs.netgate.com/pfsense/en/latest/multiwan/considerations.htmlExcuse me, I missed your answer somehow!
Gateways are different, different subnets.
On the first link of provider # 1 there is a white IP address, on the second link of provider # 1 the IP address is gray, as a temporary one.Thank you, I'll check!
