Firewall is blocking calls out from SME right after boot

« on: January 17, 2009, 08:25:35 PM »

I start up my SME every morning about 6:00 AM and my firewall is detecting voluminous hits on my firewall log from SME trying to contact some IPs with a destination port indicating DNS, but calling from anything but a DNS port.

Here is the log:

SPT is the source port and DPT is the destination port.

Code: [Select]

I don't get any hits the rest of the day, but I sure wish I knew what was going on here. Any tips or clues would be appreciated.

Re: Firewall is blocking calls out from SME right after boot

« Reply #1 on: January 17, 2009, 09:08:50 PM »

hi

don't worry about it.. it's normal traffic.. as you've pointed, it's DNS traffic.. it's your SME that makes dns requests..

configure your firewall not to block outgoing traffic directed to *.*.*.*:53 udp coming from SME

Re: Firewall is blocking calls out from SME right after boot

That sounds reasonable.

Just out of curiosity, why is SME making all of those inquiries and why all the different ports? Some of them are to the same IP and port, but from a different port. Why is that?

dnscache is contacting the root name servers as the first step in resolving a DNS query.

Randomisation of the source port is a necessary security feature.

Google for "DNS random source port" and you will find out what happens if the resolver does not use a random port number.

Once again I am getting voluminous hits against the firewall from SME, but this time instead of DNS port 53 being the target, the target is port 80 for HTTP. What's going on here? Should I allow this too?

Get rid of your firewall. SME server doesn't need a firewall between it and the Internet.

That's a pretty dramatic claim. Could you explain that? It would also help if you could explain why SME wants to access HTTP pages on its own.

SME server is designed to sit right on the Internet. Many, many thousands of servers are so situated.

I supposed that's right. You can configure SME to be a firewall itself. I am in server only mode.

I am running another Linux distro as my router, called Smoothwall Express. I wonder if I can make SME run like Smoothwall and especially with the multiple LAN ports isolating a "DMZ" zone.
