Re: IPSEC with 2 WAN interfaces

I've tried both methods. Mangle->Output->if src-address=2.2.2.2 then mark routing to ISP2. No success.
Routing lookup (as you mentioned) no success.
Despite of these settings, the router wants to route the ipsec traffic always to ISP1. Very strange....

And what about the uplinks? Using VRRP, how should I configure the 3rd switch? Bridging?

I'm not sure, but as I know, LACP cannot be set when there is only 1 connection between switches (sw1->sw3 and sw2->sw3). How to set LACP in this scenario?

Yes, you are right, all traffic is blocked between the 2 LANs. My big problem is that the name server resolves the external ip address of the LAN1. From LAN2, this public ip is on the same router (but on the other interface), and as I can see, the router interprets this traffic as INPUT. But in this...

Ethernet card: no link in Mikrotik OS

Hello,

I set up a PC with 2 ethernet cards (same type). The physical links ok (leds on the cards), but MT says that on one of the two cards there is no link. I replaced the network card, the result is the same. The other network card works well.

Any idea?
