Topic: blocked by remote server.

[crazybob]

There is a remote sme server that I was able to access until late last week. I was connected via openvpn, and in the process of transferring some files to a work station on their network when I lost connection.

When I tried to re-establish connection, it failed. When I tried to access their server-manager, (which I used to be able to) it fails. I went to the location of the remote server, and checked the iptable log, and is shows I am being denied.

I am new to iptables, and need some direction

The remote server is either 7.3 or 7.4

Thanks

You shouldn't need to know anything about iptables (and the openvpn packets shouldn't be being blocked). I presume you are using a contrib, and the contrib should be doing all the iptables changes necessary to allow the contrib to work. File a bug report against the contrib.

Thanks Charlie, but it is not just openvpn that is being blocked from my server. it is everything. I cannot even ping the remote IP, or ssh into it. I can shh into another server and ping the problem server with out a problem.

What happens when you do a tracert to the remote server ?

traceroute to xxx.xxx.xxx (xxx.xxx.xxx.xxx), 30 hops max, 38 byte packets

We are both using the same isp and have static ip's, and are only about 2 mile apart.

It's not a diagnostic approach, but it could save time.
Did you reboot both servers ?

[crazybob]

Thanks Mary,
I did reboot the remote one while on site, and the local one when I updated software over the weekend.

Do a port scan on the remote server.
Anything happen with your ISP or router ?

Hi Mary,
This is only between these two servers. I can connect to many other servers, and other servers can connect my problem child. It appears my ip has been blocked.

The remote server is either 7.3 or 7.4

Thanks

well, unfortunately my crystal ball is broken and I can't help you but you could help us to better understand, for example if:
- are the servers in server-only mode? or in server and gateway?
- did you install any contrib on the target server

thank you

[crazybob]

The remote server is server-gateway mode. I know awstats, openvpn, and vmware are installed, and have been running flawlessly for over a year.

The server is SME 7.3 Last update unknown
