iptables

Hi guys,

I am working on a iptables rule to apply after my shorewall script has initialized my firewall. I want a spicific IP (10.0.1.19) address in my lan to be redirected to 10.0.64.1 except if it is going to paypal.

I have the following rule, and that works like a charm

iptables -t nat -A PREROUTING ! -d 1.2.3.4 -s 10.0.1.19 -j DNAT --to 10.0.64.1

My problem is that paypal uses multiple ip addresses, and I am not allowed to have multiple IP-addresses.

On top of this problem I would like to know how to remove the rule again, without having to restart shorewall.

Kind regards

Tax

Hi all, I'm setting up port forwarding for an L2TP VPN connection to the local Windows 2003 VPN server. The router is a simpel Debian machine with iptables. The VPN server works perfect.

I was thinking initially needing to do a reverse proxy or something so I could get some SSL/TLS traffic look like it is being terminated at a server and IP address in the AWS cloud, and then that traffic is forwarded onto our actual web servers that aren't in the cloud... I've not done much iptables… >>> More
