2xISP -> one for www other for rest - problems with routing

RouterOS Beginner Basics

Hi,

I would like to connect 2nd isp (first is working at the time) to my Mikrotik Router (2.9.48).

I’m doing this in this way (ofc IP is assigned to ehternet card):

ip firewall mangle add chain=prerouting protocol=tcp dst-port=80 action=mark-routing new-routing-mark=GTSwww

ip route add gateway=xxx.xxx.xx.xx routing-mark=GTSwww

And I cannot force this rule

dst-address=0.0.0.0/0 routing-mark=GTSwww action=lookup table=GTSwww

There is no action and table “command”…and I’m reciving:

Invalid route configuration: No gateway

Could you help me ?

Where are you inputting:

dst-address=0.0.0.0/0 routing-mark=GTSwww action=lookup table=GTSwww

ip route add dst-address=0.0.0.0/0 routing-mark=GTSwww

ip route dst-address=0.0.0.0 gateway=xxx.xxx.xxx.xxx routing-mark=GTSwww

Hm… so it’s should look like this:

ip address add addres=xxx.xxx.xx.xx .....

ip firewall mangle mangle add chain=prerouting protocol=tcp dst-port=80 action=mark-routing new-routing-mark=markName

ip route add dst-address=0.0.0.0/0 gateway=xxx.xxx.xx.xx routing-mark=markName

After adding last entry www stop working
What is the reason?

I think that I have found problem - but not the solution

After adding ip address i do not have access to it outside the network (even ping is not working). But what is funny - the same config works fine on other router (also on MT). I even switched network card - still this same situation. What da f… ?

do you nat your network, is it set up correctly for both gateways (interfaces)

Janisk this was a good hint - i did not set nat for 2nd gw.

But, it is still not working.

Now my nat is like that:

chain=srcnat action=src-nat to-addresses=xxx.xx.xxx.xx to-ports=0-65535 out-interface=ext0 src-address=192.168.0.0/24 icmp-options=0:0

How should look nat for 2nd gw? Only routing-mark or with address class?

GW1:
/ip firewall nat add chain=srcnat out-interface=ext0 action=masquerade

GW2:
/ip firewall nat add chain=srcnat out-interface=ext1 action=masquerade

These are NAT rules.
