Hello Everybody!!

I've faced with very mysterious and very annoying bug with 6120, 605 and 8411 routers ~5 years ago.

Config:

wan1 Dynamic IP

wan2 Dynamic IP

wan3 PPPoE

+pptp client interface

wan1, wan2 and wan3 Included into Load Balance

Policy Routing 30+ IP Ranges setuped to pptp client gateway as Priority

Examples of IP Ranges: 68.232.34.217/32 69.195.160.0/19 104.18.20.0-104.18.34.0 104.244.40.0/21 151.101.108.156/30 151.101.244.156/30 151.101.40.156/30 ...etc

From the first minutes everything works fine, but few time later (minutes, hours, days) some IPs from LAN are going to uses pptp client gateway AS DEFAULT! 

Tracert still works correct but all TCP 443 traffic looks to pass through pptp ONLY. such sites as Speedtest.net indicating access through pptp wan ip!

At the same time all other LAN IPs continuing works correct, 0.0.0.0/0 to wan1,2,3 via Load Balance and Policy Routing 30+ ranges through pptp.

I've tried to use WAN pptp client instead of pptp client from VPN menu. The same problem.

As I understand since some time of correct operation Load Balancing began to use pptp client interface as default for some LAN IPs. 

So I need help! Tracert can't detect the problem in the route. LAN IP that got the bug could found that all websites will show geo-location by pptp client location. Also traffic speed will be strongly reduced (my pptp is slow). Can anybody add 30 routes via Policy Routing to PPTP Client of PPTP WAN? +other NON-pptp interfaces to Load Balancing.

I solve the problem using Static Routing for the same IP ranges. But it is not so reliable as Policy.... ((

Best Regards.
