I am having trouble interpreting some inbound TCP/UDP test results that I performed tonight via Vuze and eMule. I used to have no issues opening and forwarding ports and used to be able to pass all tests. I made some changes to my config that centred around Loopback and DNS IIRC. I am not certain, but it seems my issues may have start around then. [circa two weeks ago]
I am on a fixed wireless connection via a Draytek Vigor 2910VG cable router. I have the ports correctly setup on the router, verified using GRC Shields Up while Comodo was switched off.
I have static IP for all my machines behind the router and do not use DHCP or DNS services. OpenDNS is manually configured on all machines and Google DNS is setup as a fallback.
I have attached some screenshots: my global rules [GR], recent firewall events focused on the time I tried to test my inbound connectivity using Vuze [CFE] & a ping/traceroute that caused the Vuze firewall events in Comodo [pingTR]
I have a self-taught knowledge of firewalls and networking and would consider myself at a reasonable level, but this just has me baffled. My connection sometimes just seems to hang, almost as if it is ‘waiting for something’ I will get a timeout and then I hit reload and the page comes up just fine.
One specific question I have is as regards DNS…at present I allow each machine’s static IP outbound to my DNS zone on port 53, is my global rule allowing inbound from the DNS zone to port 53 necessary? I have researched conflicting views on this.
If you look closely in the botom right of the ‘pingTR’ screenshot, you will see that my NAT is rated green, I have a green connection on the transfer windows and you can also see I am getting a reasonable speed and I am hovering around my user configured upload limit. This is despite the disastrous ping/traceroute log.
My hunch is that I have Comodo incorrectly configured on the ICMP protocol [I do not allow anything right now] and I think I may have it incorrectly setup on DNS and possibly Loopback also.
Sorry for going on, but I thought I would be helpful by giving as much info as possible. If there is anything more you need do not hesitate to ask.
Really hoping the sages here can help me!!
