Well I've solved my DSL/Linux issue thanks to a very kind TCLUG member. I now have a Cisco 678 and Red Hat 7.3 up and running. The 678 is doing NAT and I'm trying to get sshd working on the RH box behind it. I can SSH to localhost, and my private IP on the LAN and it works fine, so I think SSH is setup correctly. I added a line to the NAT table on the modem for port 22, pointing it to my local IP. When I type show nat it looks like this: Local IP : Port Global IP : Port Timer Flags Proto Interface 10.0.0.3:22 209.98.143.114:22 0 0x00041 tcp eth0 wan0-0 When I try to connect to my public address (or ip) it stalls. I ran ssh -v -v -v and it gets just as far if I try to connect to a box that doesn't exist. So I've narrowed it down to the modem (I think). Are there any tricks to get the 678 to correctly forward those requests? How can I troubleshoot this or test it? Thanks, Dan
