Hi, How can i use rsync beetwen 2 computers in diferents networks? I put an addicional ip address in the router to host this forward that i will call _ip2 Computer A = 139.82.xxx.xx1 Computer B = 192.168.1.4 router_ip2 = 139.82.xxx.xx2 router_ip2 and computer A are onde the same network router is on both networks, of course rsync uses port 873 i guess this is what i want to run: rsync -razvp localhost:/home/ 139.82.xxx.xx2::backup/daily 139.82.xxx.xxx -> router -> 192.168.1.4 : 873 i tried: iptables -t nat -A PREROUTING -d 139.82.xxx.xx2 -i eth0 -p tcp --dport 873 -j DNAT --to 192.168.1.4 ...but didnt work thanks
