Hi everyone!

I'm probably being really stupid with this one, but some help would be apprecited,

I have two wan connections, one comes direct into the mikrotik, one into the other router

What I want to do is to be able use the talk talk wan as a failover / load balancing gateway (so it looks like this:)



I have connected the LAN port of the talk talk box into eth2 on the mikrotik

This is the IP Scheme

LAN1 (mikrotik) : 10.1.1.0/16
LAN2 (talk talk) : 192.168.1.0/24

so I need to be able to get anything in LAN1 to talk to aything in LAN2 (such as the talk talk routers web iface), i tried this :

/ip route add dst-address=192.168.1.0/24 gateway=192.168.1.1

but when I run a ping from my 10.1.1.1 client PC or the router command line I still cannot ping anything on the talk talk lan. ( so I'm clearly missing something) and the router says unreachable in winbox

Once I've done that I need to be able to use the talk talk as a load balance / failover set up, I tried this:

/ ip firewall address-list
add list="Allowed-Internet" address=10.1.1.1/16 comment="allowed use of internet" disabled=no

/ ip firewall nat
add chain=srcnat action=masquerade out-interface="WAN - 01" src-address-list="Allowed-Internet" comment="Gateway 10.1.1.1/16" disabled=no
add chain=srcnat action=masquerade out-interface="WAN - 02" src-address-list="Allowed-Internet" comment="Gateway 192.168.1.1/24" disabled=no

/ ip route

add dst-address=0.0.0.0/0 gateway=10.1.1.1 scope=255 target-scope=10 routing-mark="SSH traffic" comment="" disabled=no
add dst-address=0.0.0.0/0 gateway=10.1.1.1 scope=255 target-scope=10 routing-mark="Unknown traffic" comment="" disabled=no

but because I can't get the routing right, I can't use the 192.168.1.1 gateway and send some traffic via the talk talk router,

any help would be appreciated!

thanks,

Which is the ip address of talk talk? The static route for 192.168.1.0/24 should point to talk talk ip address

Internally the IP address is 192.168.1.1,


Thanks for the reply

Hi,

Let's try this way:
*Delete all your config related to WAN-2
*Add IP address from 192.168.1.0/24 network to WAN-2 interface ( lets say its 192.168.1.100)
*Set static route to 192.168.1.0/24 via 192.168.1.1 ( MT should create additional route with interface label as gateway and preferred source address 192.168.1.100)
*Create masquerade and select WAN-2 interface as out.interface

Now you should be able to talk between 10.1.1.0/16 and 192.168.1.0/24 networks

After this you should try to make your routing/balancing/fail-over rules.

Thanks for the reply,

I've done all of the above, other than the masquerade rule - how would I add that?

Thanks,

Rob

Hi,

/ip firewall nat
add action=masquerade chain=srcnat out-interface=WAN - 02

Should do the job.

Ran all of those,

Can ping the talk talk router (192.1.1.1) from the mikrotik,
masquerade is turned on for wan02
static route created between the two subnets

Still cannot ping anything on the 192.168.1.0\24 network from the 10.1.0.0\16

I can ping from 192.168.1.1 to anything on the 10.1.1.1 though - I added another route on the talk talk router and that seems to have worked, just cannot get from mikrotik lan to talk talk lan...

very odd.....

Hi,

here's my config

ICMP traffic gets marked on mikrotik and goes to talk talk router which sends it to the internet.
I can ping talk talk from 10.1.0.0/16 subnet.
ether1 always leads to the internet.

mikrotik

talk talk

Can you post routing table again? Also, can you disable all traffic marking and routes for marked traffic? Just leave 2 default routes for WAN1 and WAN2.

Heres the routes I have

[quote="b1863515"]Hi,

[/code]

which section is this in?

Hi, that's the routing table of the router you call "mikrotik" in your diagram

Hi,

Code: Select all

0 A S  dst-address=0.0.0.0/0 gateway=192.168.1.1 
        gateway-status=192.168.1.1 reachable via  ether2 distance=1 scope=30 
        target-scope=10 routing-mark=1_icmp 

 1 A S  dst-address=10.1.0.0/16 gateway=ether3 gateway-status=ether3 reachable 
        distance=1 scope=30 target-scope=10 routing-mark=1_icmp  	NOTICE I HAD TO ADD THIS RULE TO MAKE THE PING WORK

 2 A S  dst-address=0.0.0.0/0 gateway=172.16.4.1 
        gateway-status=172.16.4.1 reachable via  ether1 distance=1 scope=30 
        target-scope=10 

 3 ADC  dst-address=10.1.0.0/16 pref-src=10.1.0.1 gateway=ether3 
        gateway-status=ether3 reachable distance=0 scope=10

 4 ADC  dst-address=172.16.4.0/24 pref-src=172.16.4.249 gateway=ether1 
        gateway-status=ether1 reachable distance=0 scope=10 

 5 ADC  dst-address=192.168.1.0/24 pref-src=192.168.1.2 gateway=ether2 
        gateway-status=ether2 reachable distance=0 scope=10 

[/code]

which section is this in?

ahh ok,

I've just added the icmp route in,

still no joy
