this is my problem:
I have two ISP live ip addresses coming into a routerboard 500 with 3 ether ports.
The ether 1 is a diginet x.x.x.216/29
the ether 3 is ADSL y.y.y.128/29
SRC-Nat masquerading is enabled to allow private ranges to browse.
The mikrotik does DST-nat to 3 networks private range
Each private range ip has 2 live ips
I have a problem i can use a default gateway to access only 1 ISP at a time.
This is to say only if 1 gateway is enabled can i access the servers via the live IP. I need to be able to hit the servers on the private range from both ISP's all the time
I think i need to use traffic marking but am not sure how to implement for incoming traffic. (perhaps policy routing)
Are there any other ways to do this ???
I need to go live with this site in about 4 days - getting quite desperate now ...
Hope you guys can help
