ISP1 is a HEX on a fiber with static IP, ISP2 is a LTE ATL18, linked with a wireguard, totally functioning (ping OK) The problem now is that 12345 and 23456, the two WAN ports bound to the NAT table, are random, that is, if the NAT table expires. Make them stand-alone ports. ISP1 is a HEX on a fiber with static IP, ISP2 is a LTE ATL18, linked with a wireguard, totally functioning We’ve created a temporary solution for one of the services by allowing internal routing for one specific port plus added a local dns entry for the guest network. What I think is that if the PC B ask for the public IP:port the So if you have strong reasons to connect multiple non-Mikrotik L2TP/IPsec clients to the same L2TP/IPsec server from behind the same public IP, Even though all other parameters of the IPsec policy are the same, the NAT-T UDP ports cannot be, because the NAT router at the client side has seen that it has two UDP sessions from two clients to The scenario I currently have is: Wireless1 (2Ghz) & Wireless2 (5Ghz) are both in a bridge (Wifi_Bridge) and all Ethernet Ports are in a Bridge (LAN_Bridge) respectively. add chain=dst-nat action=dst Mikrotik router - how to configure NAT and 2 VLANs on one eth port?
