DFL-800: Second PPTP connection not working
« on: May 27, 2016, 03:58:50 AM »

Hi,

I have 2 internet uplinks, through two different ISP. Wan failover is working ok, also PPTP through wan1. But i'm not able to make it work through wan2.

This is my setup

WAN1 (DHCP) -> cable-moden (so, direct connection to the internet)
WAN2 (static 192.168.0.207/24) -> (192.168.0.201/24) DSL router -> Internet

Ther'es also an VLAN, but it'r not related.

DFL-800:/> routes

11 Allow *:0.0.0.0/0            wan2:192.168.2.207     "all_services"

PPTP works OK through wan1, but users can't connect from the internet to WAN2 PPTP Server (port 1723 redirecter from the DSL router). This is logged:

2016-05-27 12:54:10   Warning RULE 6000051   Default_Access_Rule   TCP   wan2 XX.XX.XX.XX 192.168.2.207   4132 1723   ruleset_drop_packet drop ipdatalen=32 tcphdrlen=32 syn=1
2016-05-27 12:54:10   Warning RULE 6000051   Default_Access_Rule   TCP   wan2 XX.XX.XX.XX 192.168.2.207   4132 1723   ruleset_drop_packet drop ipdatalen=32 tcphdrlen=32 syn=1

But they can connect from any IP address between WAN2 and the dsl router (192.168.2.0/24).

What i'm missing?

Regards,

I don't have much experience on DFLs.

Might try swapping WAN ports and see.
Check the user manual for any configuration help. Or phone contact D-Link support on this...
