Blocked IP

Hi,

I have a server that can't go out to the internet, VMs hosted on it are working properly so I suspect that something is blocking the servers IP, if I change the ip it works fine, any suggestion on how to find what's blocking it? Thanks

There might be a bunch of reasons.

Check if you have configured a dns on your server and also check if there is a policy allowing that kind of traffic

There is dns on the server and it's working, also I don't have any policy preventing it from reaching the internet. I have another server within the same range, also a host and it's working without issues

how can I monitor the IP to see if something is blocking a specific IP.

 

Thanks

Hi Ali.

 

Are we talking about a vmhost server (with VMs) behind a fgt - VMs can connect to the Internet, but not the VMhost itself?  Standard troubleshooting should applied - what host/network info (subnet mask/default gateway) is configured on the VMs vs the VMhost - Can you ping each other IP (VMhost vs FGT)?  From the fgt side, are both the VMhost and VMs in the same subnet?

Dave,

Yes it's VMhost server, both hosts on the same subnet, I am able ping fgt from both hosts, same gw (the fgt fw) on all machines and it's working fine. I am able to ping from both sides fw and the host. Thanks
