Greetings

I'm having an issue with subnetting on my MicroTik router.

I am attempting to have two subnets comunicate with each other. This is something i've done many times before without issue, however tonight stuff just isn't working. :(

Router has 5 ports...

Ext1 1 = WAN
Int1 = Office1 LAN (10.1.20.1/24)
Int2 and 3 = Empty
Int4 = Office2 LAN (10.66.89.1/24)

I am able to ping from a host on Office1 to the gateway on Office2 and thats it. I can not ping anything on Office2 other than the gateway, cant ping any hosts on Office2.

IP / Interface / Route settings: http://i.imgur.com/g4Nmg.png

When i use the ping utility within MicroTik i cannot ping either gateway from the other...

Ping from Int1 to 10.66.89.1 on Int4: http://i.imgur.com/b6iPy.png

Ping from Int4 to 10.1.20.1 on Int1: http://i.imgur.com/f57xg.png

Using the same utility, I can NOT ping From Int1 to 8.8.8.8 (Google's DNS)

I also can NOT ping From Int4 to 8.8.8.8 (Google's DNS)

Here is a screenshot of this. The result is the saem when selecting either interface.

The only interface which can ping it is Ext1 as thats the WAN.

Hosts in the Office1 subnet have FULL internet access, DNS, can ping google's DNS, everything is dandy. For whatever reason the router cant though... :/

Yes i run several different servers / services which require multiple public IP's.

THat should not make any difference here.
