Re: IPsec portforwardning

It should be possible to do that. Using IPIP over IPsec (or even plain) you can transport any IP traffic from router A to B and B to A, when the routes are correctly set. Of course you should check some basic things with ping and traceroute to see what works and what does not work, so you can find ...

Re: IPsec portforwardning

Direct IPsec tunnels are always a bit tricky because they work differently from normal routing. I recommend using a Tunnel Interface instead. Make a IPIP or GRE tunnel with IPsec transport, and a /30 network address, then insert static routes for the networks you want to use. With this setup it is ...

Re: Route problems.

No, not with dst-address! That is not a matching criterion for the different paths. Use source-address for the matching. Match on source address of one interface and contains the default route for that interface, put the default route of the other one in the normal table. Dont Work :( Sure it works...

Re: Route problems.

Don't put 2 default routes in the same table and expect to use both. Think about what you want with the second interface and use either IP->Routes->Rules and two different routing tables, or match all your traffic on the second interface and use a set nexthop. like this ? [admin@MSBR-Core01] /ip ro...

Re: Route problems.

This is not required, with route tables you can define a rule based on source address. But tagging the traffic and selecting a nexthop in a filter rule is possible as well. Can you maby give a explem ? I have this Routes [admin@MSBR-Core01] > ip route print Flags: X - disabled, A - active, D - dyna...

Re: Route problems.

This is possible when you setup a second routing table for your second WAN and
then define IP Route -> Rules to send the traffic to the correct routing table.

So i can make a preroutning under mangel ?

Re: Route problems.

As I see it, the router could just manage both my WANs, I will not double my download or upload speed. But just might forwarede my port from the WAN side to the LAN side.
