hy i have a mtik 5.7 and on this running a pptp server to shear another people internet, the people connecting over vpn.. For first i use a news group over outlook we say the address its sss.com (on ip 1.1.1.1) from a first provider settings, and second settings are ppp.com (on ip 2.2.2.2)... now its the problem i use sometime a internet connection from one provider and the second, on my pptp mikrotik server.
Now the users have a settings on outlook set on sss.com for reading newsgroup if i change my internet connection(provider on mtik) than don't work the reading on sss.com only on ppp.com... How can I keep the settings on user pc to nothing to change. I have try /ip firewall nat add chain=dstnat dst-port=119 action=dst-nat protocol=tcp to-address=2.2.2.2 to-port=119
