[Lsalas TNTPOKER]

I have a bridge-firewall whit iptables, this is running very fine, but I need check the attack and port scan, incoming to my server through to my bridge-firewall, this servers is after of my bridge-firewall, I put portsentry and snort in my bridge-firewall, but portsentry only detect the scan ports localy, but I need detect the incoming port scan. Snort , well... snort dont say nothing, I think that snort not run fine in a bridge.... I�m not sure. My configuration with snort is fine,I know because  this is running fine in other servers. you have some idea? I need check the attack and portscan incoming to my network and then make a dinamic firewall.
