PB, Either the green and orange address range needs to be changed. With your subnet mask, you arer telling that IPCOP that particular interface has a range of 255 addresses. With your addressing, you have basically told IPCOP that it has two interfaces with exactly the same address range on it. Poor old IPCOP will end up with a headache. Suggestion: Retain the current subnet masks of 255.255.255.0 on all interfaces, as I don't feel that you want to get into other subnet masks at the moment. Change the IP address range on the orange interface to 192.168.2.x. Alternatively use the 10.x.x.x or 172.x.x.x address range. I believe you will find it will make a major difference. As a guide, look at www.netintegrity.com.au/webindex.html . This has a complete guide for what you are trying to achieve, including setup of IPCOP, mail & web servers, port forwarding, external service etc. Everything else you have said, sounds fine.
