Routing and Remote Access: No Ping after configuring RRAS

hello all

i have configured vpn on windows server 2012 r2, have 2 network adapter cards, card1 internal non routable ip , card2 external public ip.

i have cisco linksys smart wi-fi: vpn passthrough enable, pptp port 1723 on gre port 47 on linksys router.

problem:

after configuring routing , remote access service cannot ping external ip network card, ping result says: general failure, general failure, general failure, general failure.

if disable routing , remote access can ping external ip on same server.

and when try access vpn locally, can access without problem, when try access vpn outside give me 807 vpn error.

windows firewall disabled on server 2012 machine. symantec endpoint protection (unmanaged) installed on server machine have disable it, , created firewall rule allow traffic on network adapters.

i appreciate if kindly me resolve issue in vpn, sometime works fine , on next day stop working , stop ping external ip.

sometimes can't ping external ip, vpn works fine when access out of office.

thanks,

hi,

according description, understanding vpn randomly stop working outside client error 807.

error_vpn_disconnect 807:
network connection between computer , vpn server interrupted. can caused problem in vpn transmission , commonly result of internet latency or vpn server has reached capacity. try reconnect vpn server.

wondering if there other server role has been installed on vpn server. please provide ipconfig /all , route print results of vpn server if possible.

best regards,
eve wang
