Routeros 4 951ui2hnd stopped traffic on vpn pptp?

Question

VPN

The connection to the vpn pptp provider was configured and worked for about two months without problems, now the connection is rising, there is no traffic through it. Directly without a router from under win the tunnel rises and the traffic goes. And if you ping using the pttp interface, then there is a ping. The same settings, the 3g modem is connected in the nat settings, I specify allppp, everything starts up instantly. When changing the nat interface to pptp, no traffic goes through the tunnel.

Answer 1

It doesn’t go, get used to such questions, draw a diagram, lay out configs (routing), lay out firewall rules, NAT rules.
