Packet snooping & diagnosing refused connections to secure web sites

[Sidewinder]

Hi peeps,

Getting terrible trouble connecting to a secure website via my router & ISP.

Can connect via 3G on all devices.

Cannot connect hard wired or wifi from router.

No error messages that mean anything.

I can ping & tracert to the site in question OK.

Open to suggestions & ideas!

 

[steptoe]

what OS/Browser are you using?

 

[Sidewinder]

Win xp pro at the moment with Chrome, same with IE, same with win 7 pro chrome & ie.

same with Ubuntu & ff too

 

[steptoe]

well, thats me out then,

I was going to suggest that some sites take offence if you dont use IE, :|

 

[Sidewinder]

You know the site, you are using it too, just with a different user name & password, can't get at the site emails either!

 

[steptoe]

ah, I cant access it either, keeps timing out on me on certain pages.

I can only access the front-end so to speak, cant access the modified mail pages. :|

 

[Sidewinder]

I can't even get past the login page!

 

[steptoe]

right now neither can I,

we did try to warn him.! :slap

What antivirus are you using, I use Avast and that gave me problems which I managed to sort.

LINUX

Not using any AV on Linux-Ubuntu, problem still there!

 

[Steve3948]

Well the router is the issue then if you tried that lot.

It must be your password to IP and Address.

 

[Sidewinder]

User name & password are ok as they work on the xp pro machine with Chrome via 3G connection.

Can't understand how the router can affect only one site.

 

[Steve3948]

So you can access other sites through your router and ISP without the 3G attached.

Maybe you need to open up a port on the router, my son had an issue with a game site and I needed to open up a port for it.

 

[Sidewinder]

Looked at port opening, did not seem, to need it, after all I am only logging into a https://www. Website.

It was working up to 3 days ago fine.

Can't, recall, any updates on win since then, plus as Ubuntu is affected, along with ios5 then it can't be a win thing.

No router updates for sure.

 

[Steve3948]

Maybe Firewall on router.

Have you tried a reboot of your router, I recall I had a similar issue and reboot sorted it.

 

[Sidewinder]

Rebooted and short of a factory reset not much else I can think of.

Oh there is a fw on the router, but can't see any settings that will block the access

 

[Sidewinder]

Anyone able to access & analyse Wireshark logs, if, I post one from Ubuntu connected directly to the Virgin media modem & one connected to the Draytek to see what the difference is?

It's just a load of nonsense to me!

I will try to capture the event of logging into the "suspect" website.

 

[steptoe]

the only time I have ever used wireshark is for penetration testing, network attachments or to decypher wi-fi networks, Im not sure they tell you a lot about remote servers,

I could be wrong though. :|

 

[Sidewinder]

It is capturing all packets between myself & the remote server, I'm hoping it will help diagnose the issue as if I can't I am well stuffed with regard to this site as it will mean shutting down my whole network to access it, or using 3G all the time, which is just a non starter, basically i will have wasted my time & money!

I can't see what is wrong, the server is fine, the connection is fine from the Virgin hub, as soon as I put the Draytek in it all stops!

I can't find any port blocking in the Draytek.

The only thing I can think of is the site blocking the IP as it is not the same as the WAN IP?
