Resolved Can't ping Ubuntu server from outside network

[Pagemakers]

Just taken another server with 1&1 IONOS UK.

The Linux server is running Ubuntu.

Whenever I ping the server IP or any domain from outside the network I get this:

PING xx.co.uk (77.xx.122.xx)
Request timeout for icmp_seq 0
Request timeout for icmp_seq 1
Request timeout for icmp_seq 2
Request timeout for icmp_seq 3
--- xx.co.uk ping statistics ---
5 packets transmitted, 0 packets received, lost 100.0 %

Why am I getting all the timeout errors? The domains and server itself work fine.

Hi Pagemakers,

Could it be a firewall outside of the server, e.g.: Edit a Firewall Policy - IONOS Help ?

 

[Pagemakers]

I don’t see anything on the 1&1 control panel to affect this.

Can you check if you can allow ICMP? Ping is set by the ICMP flag not TCP or UDP,
Or maybe your hoster has a firewall on top of yours?

All sorted. I needed to allow ICMP to 1&1’a firewall.

Thank you.
