Problem with DNS and Firewall
« on: June 30, 2009, 09:55:35 am »

I am not sure if this is a problem or it is just me that dont understand the firewall settings. The other day i was trying to access The page didn't load. I tried to do an nslookup on the address from my local computer and i got this response


;; Truncated, retrying in TCP mode.

When i run the same command from a computer not within the network i get a correct response, it also works if i do the same request directly from the ebox server. It seems that the ebox firewall is blocking or not correctly forwarding dns request with the tcp protocol to the local network. In the case of megavideo the size of the package is to large to be sent with udp and therefore the dns requests fails. Hope that someone can confirm this as i am not totally sure of it.
