Hello -
I'm having a peculiar problem - I have a RB450G running RouterOS 4.11.
This router is the main router for this company I support. They have an internal Microsoft RRAS server to terminate VPN traffic.
1) The RB450G is natted with 2 x dstnat:
- PPTP (1723) to the internal RRAS server
- GRE to the same RRAS server
2) The IP Firewall accepts (input) both PPTP and GRE
Situation:
- Some people can connect without any problems
- Some people can connect, but then after 1-2 minutes it drops
- some people cannot connect at all.
I initially suspected either user's routers or ISP - But as it turns out, if I replace the RB450G by a generic linksys with NAT forward 1723 and PPTP pass-thru enabled, it works perfectly for everyone!
ANY suggestion welcome.
Thanks -
