Hi I wonder if I can get some advice please. I am familiar with mikrotiks but having a nightmare.
I have recently moved a datacentre to another one and the servers in questions are hyper-v replica servers.
I have managed to get them on the internet and dns records are pointed to the right IP.
I have having problems forwarding the replication traffic from the internet to those servers behind the mikrotik.
The port in question is 8888 and the the internal IP address of the replica server is 192.168.88.30.
The replica servers have their own IP range and a DC which dishes out IP to them. the subnet is 192.168.88.1/24.
The servers go to their own mini switch and then ports through to mikrotik port 9 which is internet facing.
The mikrotik in question also has other ports enabled which provide Leased Lines to our customers and they have separate external IP addresss.
I have been trying to configure the NAT but been failing.
I have created a dst-nat rule to forward all the traffic to IP address of the replica server which is 192.168.88.30 but its still not letting the traffic through.
Can someone point me to the right direction please.
thanks in advance.
Kash

Re: Port Forwarding Advice Needed
In addition to the DST NAT rules you would need to allow the traffic in the forward chain (IP Firewall / Filters).
Re: Port Forwarding Advice Needed
I cannot get this to work. I'm trying to forward a port for Plex but the service is not able to get onto the WAN.
In action I chose.
And here's the output from the terminal.

Re: Port Forwarding Advice Needed
PS: Put all your dst-nat rules before the masquerade rules.
