On my Mikrotik I use 2 WANs from differen ISP.
Let say I have public IP 18.104.22.168 on WAN1 and 22.214.171.124 on WAN2
All my traffic is routed without any routing mark through WAN1. But we have VLAN for guests and I set mark-route and src-nat masquarade to use WAN2. Of course in IP>Router WAN2 has route mark set to "route-guest".
Everything works fine except I can no longer use WAN2 public IP to access Mikrotika with Winbox and I can't use WAN2 IP for DST-NAT.
I know that is probably problem with marking traffic but I don't know how to do that.
