odd behavior when put behind a router

I was installing/configuring gentoo through ssh on my home network and I got everything working! (pure-ftpd auth: mysql), mysql, php, apache2, ssh, everything worked! I could run #reboot through ssh and the system would reboot and I could ssh it a few minutes later. About an hour ago I moved it to a faster connection behind a linksys router, and now I'm getting TONS of problems.

First of all, I tried to access phpmyadmin and it went SUPER SLOW, and I mean SLOW! My plaintext index loaded as quick as normal, but not phpmyadmin.

I couldn't login to pure-ftpd, so I double checked pure-ftpd.conf and saw that my ip address wasn't set correctly, so I changed that, saved it. Then I couldn't get pure-ftpd to restart, so I ran #reboot through ssh, and now I can't connect to my system. I drove back to the server, logged in, logged off, and BOOM, I can ssh my system again. The problem has to do with my router, but I don't know what could be wrong. Ports are forwarded, my system's ip is static (so reboot wouldn't affect forwarding). All I can think of is maybe the router requires data to be sent from my server before my server can recieve it. The router is a linksys, and the firmware is probably horribly out of date.

Maybe a shell script that logs me in, then back out right on startup will solve the problem? Even so, I'd rather fix this without having to do that.

I'm stumped on this one guys.

Any ideas?

What kind of connection is it on? You said it was a fast one, but how fast. Fast is a really relative term when it comes to bandwidth. And are you sure it has plenty of upstream bandwidth? My server is on a good downstream bandwidth connection but it has horrible upstream speed which effects the stability of tcp connections much more.

Also you may want to make sure that your router isn't filtering some things it shouldn't. In the past I have had the SSH port open, but the router filtered it until an outgoing connection was set up.

I'm on verizon adsl 1.5/384kbps. I'll look at the filtering options and make sure nothing is there.

Thanks for the input, anyone else got any ideas?
