Hi, i’ve 2 mikrotik 3.20 on different locations.
each one has a DSL connection with static ips.
dsl modems are running in bridge mode, so both of mikrotiks has public static ips.
(ie,
router1 has 88.88.88.88 with gw 88.88.88.1
router2 has 77.77.77.77 with gw 77.77.77.1 and ips are static)
i currently have, a l2tp server on router1, and a l2tp client on router2 ,that is connected to router1, and all working fine.
But last week, i got another dsl connection for router2, so it now have a second public static ip
which is 66.66.66.66 and has a gateway of 66.66.66.1.
now what i want is, create a second l2tp client on router2, which will connect to the same l2tp server on router1.
i know basic routing topics,but since the traffic will go to the same ip (88.88.88.88) i couldnt figure out how to do this.
ok this is last bump,and sorry for it.
i still have some hope that this can be done.
but i think iwill request for additional ip from my ISP for router1,if that post stays unanswered for a couple of days
so you basically want two tunnels going at the same time, each tunnel over a different modem - but the server only has a single IP. Yes, you need another IP to make this really clean.
You might be able to dst-nat and redirect and route mark udp/1701 and try to use an alternate port but I am not sure if that will work since its on the output chain. Maybe you can use l2tp for one tunnel and pptp for the other ? that way you can route-mark tcp/1723 and proto 47 to use one gateway and udp/1701 to use another. just a few thoughts …
router 1 - setup a dst-nat chain rule that does a udp/1702 redirect to udp/1701.
router 2 - setup policy routing to send udp/1702 traffic out gateway 2
router 2 - setup srcnat to change outbound udp/1701 to udp/1702. cant remember if you can src-nat on the output chain and have it work right. would be lovely if MT would allow IP address and port bindings for ppp type tunnels.
