Sorry to start this topic with urgent Title, but i believe as much as everything else counts in my situation "Time" has a major count!
in a network with two providers each with its own ip and gateway, how can i forward "ICMP" requests to one provider and let everything else do its normal work functioning through the other provider?
this way, when one subscriber's station is using a mean for its world wide communication that relies mainly on ping timing, will benifit from the fast reply from one provider while the rest of his/her data flow will take place on provider number 2.
I would appreciate a simple code as a jump start.
Thank you,

use routing-mark in mangle to mark icmp packets. And add route with that routuing mark to route over second gateway.

Let me get his correct:
what will be my mistakes here and what are my next steps after marking them?
Thanks,
Code: Select all
ip address add address=22.22.22.50/29 interface=WAN-ICMP
ip address add address=33.33.33.50/29 interface=WAN-Data
Code: Select all
ip route add dst-address=0.0.0.0/0 gateway=22.22.22.49
ip route add dst-address=0.0.0.0/0 gateway=33.33.33.49
Code: Select all
ip firewall add chain=prerouting src-address=192.168.0.0/16 protocal=icmp action=mark-routing new-routing-mark=WAN-ICMP
ip firewall add chain=prerouting src-address=192.168.0.0/16 protocal=!icmp action=mark-routing new-routing-mark=WAN-Data

You don't need second mangle rule.
And route with routing mark is missing
/ip route add gateway=22.22.22.49 routing-mark=WAN-ICMP
And route with routing mark is missing
/ip route add gateway=22.22.22.49 routing-mark=WAN-ICMP
Re: URGENT: protocol forward between dual providers??.......
If i said route icmp to WAN-ICMP as:
/ip route add gateway=22.22.22.49 routing-mark=WAN-ICMP
will the network automatically know data flow should got through WAN-Data or there is also another rule I must add?
thank you
/ip route add gateway=22.22.22.49 routing-mark=WAN-ICMP
will the network automatically know data flow should got through WAN-Data or there is also another rule I must add?
thank you
Re: URGENT: protocol forward between dual providers??.......
Oh I think the one masqurate rule on WAN-Data should do the job without any extra rule correct?

ok, lets try to solve it in a different way...
If you want you can give a high priority to ICMP...
for ex:
