Two questions

[dex3r]

Hi! Im new debian server owner and i cant solve two problems.
1. How to redirect port 17000 from s.domain.pl to 17000 on domain.pl. I heard something about iptables and prerouting, but I have no idea what to do.
2. I cant install GD lib on php5. After:

apt-get install php5-gd

what I get is:

Failed to fetch [FORUM CENSORSHIP]security.debian.org/pool/updates/main/p/php5/php5-gd_5.3.3-7+squeeze13_amd64.deb  404  Not Found [IP: 128.101.240.212 80]
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

with --fix-missing nothing repairs.

Thank You for help and sry for bad English.

EDIT:
Problem 2. SOLVED. Ofc I forgot to do apt-get update and upgrade... stupid me.
