Accessing IP address from other site

[girisnair]

I am using Dansguardian with squid proxy. Have 2 sites with ipsec connectivity(VPN). Now when I try to access the web server of site B from site A thru its local ip i.e. 10.0.0.0/test i get a message "The connection was reset". but when I try to access thru the public ip it works fine.
Am i missing any settings in firewall or dansguardian. Kindly help.
