Hello Everybody,
I have strange situatio, explane

I have 2 routers 1-OpenWrtBased 2-Mikrotik(RB951Ui-2HnD)
OpenWrt has 10.20.10.0/24 subnet with it own Wan connection to internet
Mikrotik has 192.168.88.0/24 subnet with it own Wan connection to internet
Between OpenWrt and Mikrotik i have link (Mikrotik interface with IP in LAN OpenWrt)
Routing between OpenWrt subnet and Mikrotik subnet success!
And lastly the OpenWrt has some servers in it own LAN, and Servers with Apache Web Servers (80 port) PortForwarding to Internet.

My problem is that I want to reserve access to Web Servers if Wan is Down on OpenWrt.

Please help me, how i can get access to servers web ressourses from Mikrotik Wan?
My Problem mainly is that Server in other subnet from Mikrotik LAN?
How I can allow this scheme:
mikrotikWAN(port 8080) → DST_NAT_TO->SERVER_WEB(10.20.10.10)

I’m guessing your problems is that the server see’s the traffic, but that the Server and/or OpenWrt router is trying to send the responses out it’s WAN instead of routing back to the MikroTik.

You may need use a src-nat masquerade so the Server thinks it’s coming from the Mikrotik router (not the greatest) and knows how to send it back.
