Have already trying to config RB750Gr3 for a week. Didn't sleep well for 4 days
But i can't make port forwarding work.
First of all i made 2 WAN Balancing with PCC - works great. Then tried to config port forwarding and got nothing (51413, 80 and 22-23 ports).
add action=dst-nat chain=dstnat dst-port=51413 in-interface=ether1 log=no protocol=tcp to-addresses=192.168.88.100 to-ports=51413
I know about firewall mangle. Made rules for input and forward chains to tag connections and made rules to route traffic into right WAN, It didn't work. So after 2 days of no luck i've tried to make clean config.
1)Made clean config from scratch, configured just WAN
(Ubuntu Server) and Eth2
(my Windows PC with Winbox);
2)Made masquerading rule for source address 192.168.88.0/24. Internet works nice on Windows PC;
3)Made no rules in Firewall (so all incoming connections should work);
4)Incoming connection from Internet to Routers Web Page is working;
5) Turned off IP Service (http 80 port), so canceled all connections from previous point.
6) Made rule
add action=dst-nat chain=dstnat dst-port=80 in-interface=ether1 log=no protocol=tcp to-addresses=192.168.88.100 to-ports=80
Aaaand - NOTHING!!!
I see 3 packets incoming on that rule each time i try to connect but no response from the server.
Firewall on Ubuntu server is turned off. And i make connections from mobile phone so there is no hairpin problem.
