Re: Strange USG100 Problem

said by TL :

I have tried everything I can think but still it don't work.

Have you tried sniffing and capturing packets on WAN side between USG and modem?

The USG 100 has the capability to do so, you can later examine the capture in Wireshark or post here for us to have a look.

Go to Maintenance -> Diagnostics -> Packet Capture

If you don't have Wireshark get it here »www.wireshark.org/download.html

I'm pretty sure that some issue/anomaly will pop up there.

Now I finally had time to make WAN-capture, when trying to play youtube-video. There are many retransmissions, duplicate acks and tcp resets. The capture file is attached, maybe someone can tell what's wrong?

I don't see anything wrong with my limited understanding of the protocols.

However, can we backtrack a bit.
1) You said you're using VDSL yet not PPPoE. What is it? PPPoA, IPoA or what? What encapsulation are you using?
2) Where is your PPP (or whatever) session terminated? (Where do you enter your ISP username/password? On the modem or router?)
3) Can you post screenshot from USG WAN config with Advanced options showing?

I can't say anything about encapsulation. ISP owns the VDSL-modem, and out of it comes normal ethernet. So I don't enter any username or password anywhere. The WAN config of the USG is just normal ethernet (MTU 1500, DHCP client enabled).

And you're getting public WAN IP on USG? Or is the modem also doing NAT?

Yes, I get public WAN IP on USG, so no nat in modem.

Any of the more CPU intensive stuff enabled on the USG, ie BWM, App patrol, Anti Virus etc. If yes, try to disable and see if it works.

I do not remember if you can turn of DoS protection on the USG like on the older ZyWALLs, but if you can look at that to.

No, there are no "extra" features enabled. Debug log shows all the time something about bandwidth, even if it is not enabled. Is that normal?
