Hello,
I am using Linux package (FC4) on this hosting. When I try to connect by SSH or by http to hosted server it is success, but when I try to connect from hosting account to external Internet hosts it fails. Even ICMP protocol does not work. It seems that outgoing conections are blocked. Is it a bug or proper behaviour ? How can I solve it ?
Thanks.

Is this a dedicated or shared host? I would look into any firewall rules that might be in use on this platform.

Package is called 1&1 Root Server II. Problem presents also when there are no rules in external firewall. I tried to reimage also Debian and SUSE. Situation was unchanged.
Here the result of some commands:
[root@~]# route -n

Try pinging something known, like yahoo.com
Also, what are your DNS servers set at?

content of /etc/resolv.conf:
; generated by /sbin/dhclient-script
search onlinehome-server.com
nameserver 82.165.235.251
nameserver 195.20.224.99
nameserver 195.20.224.234
=====================
It seems DNS works correctly because name resolving works.
[root@~]# ping www.yahoo.com
PING www.yahoo.akadns.net (216.109.117.206) 56(84) bytes of data.

Have a look at your welcome email. 1&1 requires you to validate your order before they'll unblock your servers' ports. At least it used to be that way some time ago.

Thanks a lot, it was a problem in confirming of hosting registration.
