I have VPN at work , using a Cisco PIX 515E as a EasyVPN server With Phase 1 with Isakmp , then phase 2: ESP When I run EasyVPN client 188.8.131.520 on any computer in my home network, it connected through, authentication complete, but I can not transfer any data. I then use Wireshark to capture packets. put it in the midle between my DSLModem and my RVL200, noticed ISAKMP packets(udp:500) went through, but not ESP packets. I then replaced the RVL200 with a Belkin 54G router, everything worked fine. Replaced back with RVL200, still not work , authenticate succeeded, but ESP can not go through, therefore, no connection. Im using firmware Firmware Version: v1.1.7 , then also upgraded to version: v1.1.10 .1, both didnt work. I had my IPSec VPN passthrough turned on. In the router log I found "Connection Refused - Policy violation : IN=ppp1 OUT= MAC= SRC=69.20.XXX.XXX DST=70.48.XXX.XXX LEN=112 TOS=0x00 PREC=0x00 TTL=56 ID=2650 PROTO=ESP SPI=0xa52269cd " Please advice!!!
