Hello,
We have installed multiple Mikrotik routers on remote locations, which are VPN connected to RHEL linux server with PPTP client. Time to time someone of routers produces this error and generally everything is working fine, except one router today, which disconnect internet every 5 second.
firewall info
dstnat: in:pptp-out1 out:(unknown 0), connection-state:new proto TCP (SYN), 192.168.1.0:55668->192.168.1.42:81, len 52.
I try to change IP address of the router and with new IP address router is working fine for 12 hrs, then the error is back again, but now without disconnecting internet.
We have few dstnat rules in firewall NAT for port forward and problem is only with one rule.
Dst Port 81
To Adresses: 192.168.1.42
To Ports: 81
Maybe some advice what is wrong, I can’t find anything on internet.
192.168.1.0 is server
192.168.1.40 is router
Thank you in advance!
