Good afternoon. There RB2011 it includes 2 provider network consists of 20 + Computer literacy raised FTP server on one of the machines lokalnh.
How to port forwarding with one of the providers (external address) on the FTP server?
/ ip firewall nat
add action = dst-nat chain = dstnat comment = ftp4 dst-port = 1-8290 in-interface =
pppoe-out1 protocol = udp to-addresses = 192.168.0.198 to-ports = 1-8290
this option does not help.
if you have 2 uplinks with NAT you have to manage incoming connections so, they are leaving through same uplink they came in. Do that using mangle to set routing-marks and configure routes accordingly.
