The new DROPINVALID option allows INVALID packets to be passed through the normal rules chains by setting DROPINVALID=No. If not specified or if specified as empty (e.g., DROPINVALID="") then DROPINVALID=Yes is assumed. 2.

I have had to replace an existing setup which has a bunch of IPs Proxy-NAT''ed onto the loc segment. While I do eventually want to move them to their own segment, I have to deal with this for the next few weeks. My problem is that from a loc system I can ping the public IP of a system being proxy-ARP''d but I can''t hit it via HTTP. Nothing is being blocked according

I''m having a problem where transferring files accross our IPsec gateway to another host on a remote network is failing. I see no packets being rejected in the logs. Attached is a packet trace, showing the problem. In this case, 10.100.0.0/24 is the local network and 10.100.14.0/24 is the remote network. The trace was taken on the local gateway. In the trace, there is a set of TCP

Dear List! I use a shorewall 2.0.8 on a Debian sarge system. I use a DSL connection to the Internet (ppp0 - eth1 to the modem) and a bridge to the local lan. The bridged config i''ve made with bridge.html from the shorewall site. The Bridge is between local net and a openvpn tap device. This works. I ccan make tunnels, and a can make a lot of things through the firewall. I can get a list
