Allow port 1434 throught Openvpn

Jcook_5xdata · 01-31-2012, 07:43 AM

One of my clients can not get UDP port 1434 throught his Openvpn connection. Tcp traffic seem ok copying files, network broswing and the like. I have look in the Openvpn setting but was unable to find any setting.

Anyone have any ideas?

Is the destination a local IP address or is a domain name? The reason I ask is OpenVPN is a split tunnel and any non-local destination which is not in the remote IP range is sent through the normal Internet connection.

It is a local address I believe. I did add a host entry for that computer it trying to connect to, but it was unsuccessful. Would Openvpn stop any traffic meaning stop UDP traffic for any reason?

Not unless you made a firewall / packet filter rule to tell it to.

Nope. here is a screen shot of the error that poping up.

Untangle's OpenVPN is split tunnel, you cannot access the Internet through it. It will use the Internet connection that is local.

So you have exported the "server" ip that the client is trying to connect to?
And that server dose not have a firewall on it? (if so add the VPN iprange to the pass list)

And you have matching firewall rules allowing traffic form the VPN interface to the internal server on UDP 1434?

I smell a DNS issue...

And I'm still half asleep brain hasn't finished booting yet. Is there a downloadable copy of UPS software? The only stuff I've seen is cloud based.

Might be A DNS issue.

Jcook_5xdata,
Where is the server located.
On your Internal network or On internet?

Jcook_5xdata · 02-02-2012, 07:35 AM

It is on the internal network. I did export local dns in openvpn and add fqdn to the host file of the client that is having the issue. He is able to browse the host it is tring to connect to. Taking another look at the message i think it is have a problem ups server > openvpn > client so UPS is have a problem talk back to the client.
