Hi, this is somewhat netfilter related so I hope this is fine. I have a firewall that had the above mentioned card. I have been using this card for sometime and it works great. Last week I tried to IP alias a port for nat'ing, and the connection will come up and transfer some data then it will slow down immensly, nearly to a stand still. I tried IP aliasing the port with IP address'es in the same range and different range. Could the problem be link to netfilter and connection tracking? What could I do to pin point the exact problem. Paulo
