Hi there, This is probably a very silly question, but here it goes. I have a linux box which I am using as an internal router [2.6.18-6-686]. These machine is connected two multiple ISPs via two separate NICs. The connections are not direct, they are via PIX 501 firewalls. Both NICs use private IPs and the PIXes do address translation. A third NIC connects the machine to a LAN. The default gateway on the box is set to the private IP of PIX 1.. I am trying to get incoming connections working from both ISPs. I have apache running on the machine. Both firewalls are set to allow port 80 though and translate it to the IP of the linux box. An incoming connection to the public IP of PIX 1 works just fine But an incoming connection to the public IP of PIX 2 does not – unless I change the default gateway on the box to be the private IP of PIX 2. A trace shows the connection coming from PIX 2 and then the reply going back out on PIX 1 I have rp_filter switched off and ip_conntrack module loaded. Does anyone know how to stop this? I thought conntrack would send the related traffic back out of the route the initial request come in on.
