Hi，every one,

Please tell me what’s wrong with my vpn gate, 
I post a picture of my home net and my office net here http://www.infotimes.com.cn/myvpn.htm

I build VPN between home and office, The VPN link seems established, but I can not ping from my home pc (not the gateway) to my office pc (not the office gateway). 

I post my ipsec.conf and firewall script here, http://www.infotimes.com.cn/myvpn.htm

I find a error log :
# ipsec verify 
Checking your system to see if IPsec got installed and started correctly:
