Update did not work

[netbone]

Suddenly can´t run update on proxmox:

# apt-get update
Err [URL]http://security.debian.org[/URL] etch/updates Release.gpg
  Could not connect to security.debian.org:80 (195.20.242.89). - connect (111 Connection refused)
Err [URL]http://download.proxmox.com[/URL] etch Release.gpg
  Connection failed
Err [URL]http://ftp.ch.debian.org[/URL] etch Release.gpg
  Connection failed
0% [Waiting for headers] [Waiting for headers]

Happens suddenly on all proxmox systems - not on only one.

This looks like a network-related issue on your end, not a Proxmox VE problem. You just failed to connect to three completely unaffiliated sites.

I've already tested. I can ping all servers listed and every other site outside my network. Only update fails. No idea how to solve.

Firewall

Fine when there are working so many people inside a network. Somebody has installed a new hardware firewall with traffic filter. Now I have edited a rule and update works well -
