This morning I got my router to interface successfully with my new SBC DSL modem. I got my new network information from SBC. Here it is.
My gateway is 64.149.52.102 Static IP addresses assigned for my use are: 64.149.52.97-101 First of all, I've never dealt with managing more than one static IP address before. As for the gateway, that's always been my router (currently located inside the network at 192.168.1.1) Inside the network, my three hosts are numbered 192.168.1.2-4. I've updated my external network DNS settings (hosted through Yahoo) and everything seems to be going smoothly. Except... Here's my problem. One of my users has been having trouble connecting to my server via FTP for some time. I haven't really worried about it that much because he's the only one having trouble (I know that's horrible of me), and because he has expressed no interest whatsoever in using any of the alternate methods I've suggested to him of getting files into his webspace. I thought it might have had something about his ISP not getting along with my ISP, or something stupid like that. Now I have a new ISP. I thought I'd try things again. My router is set to reroute all requests to port 22 (FTP) to internal address 192.168.1.2 (which is my server box). However, when I try to run nmap on 64.149.52.102 (I know it's the address of my router, but it's what I always did when I had only one external static IP address), the only information I can get is that all ports are filtered. I don't even know what that means. I figure that's because it's scanning my router instead of the server under it where it's supposed to be forwarding requests to several different ports on. What I'm asking is, how can I get the necessary information from my server box (inside the network) instead of the router which serves as a gateway? If it matters, my router is a Linksys Wireless-B Broadband router. This has really got me confused. I can't ping 64.149.52.102, I can't telnet to any of the ports that are set to be open, and no matter what I try I can't get any kind of response from 64.149.52.102 - actually not any output at all. In all cases of pinging and telneting I've had to Cntrl+C to get out of it because it doesn't tell me anything. And yet mail is going through and I can access web pages on my server. My vsftpd.log file on the server even showed an anonymous login to the FTP server earlier this afternoon (after I hooked the router to the DSL modem.) This has got me very very confused.... -- gentoo-user@gentoo.org mailing list
