标题: Freegate shows a 1x1 pixel gif image
作者: spsdth一月 03, 2015, 08:31:49 下午
Hi,
When I use FreeGate in F tunnel mode, I can't open any web page through http (port 80), and I will get a 1x1 pixel gif image instead of the web page. but https is fine. switching to the A tunnel mode will resolve the problem but FreeGate is very very slow and practically unusable in A tunnel mode, at least for me. I've tested all versions of freegate from 7.40 to 7.52, all have the same problem, but it was working fine a month a go.

The interesting thing is that I've tested freegate with 4 different ISPs, and 3 of them had the above problem in F tunnel mode and only one of them is currently working fine, so I suspect that it maybe a restriction that dynaweb is applying to some regions to limit the usage of the freegate. Is that the case? does really dynaweb is restricting some regions? or is it a temporary problem that will be resolved in the future?

Thanks in advance for clarification.

is the problem still happening?
freegate will return 1px image when access to sites that in our blacklist.
but it shouldn't return 1px image for all sites.

Yes, It is still happening.
It returns 1px image for all sites, It even returns 1px image for http://127.0.0.1:8580, http://dit-inc.us, http://internetfreedom.org and all others. (It happens only in 'F' tunnel, 'A' tunnel is fine except that it is extremely slow and unusable)
But if connect to a VPN server or proxify freegate through a https or SOCKS5 server (outside of the country), then freegate will work fine, 'F' tunnel works normally and 'A' tunnel will become fast just like 'F' tunnel.
but i can't use freegate directly with my ISP.

Ok, since freegate will return 1px image for all sites (including this forum), and according to your answer it shouldn't but only for blacklisted sites, then maybe the government have found a way to detect and intercept the freegate packets and somehow managed to change them in way that the freegate user will only get a 1px image. that will effectively block us from circumventing the internet censorship by freegate.
I hope it won't be the case, If not and also dt-inc itself in not blocking us by just simply returning a 1px image, then what exactly causes this behavior from freegate?

Dear administrator, dweb
At first, I do appreciate you and your team's constant efforts in developing and advancing this amazing anti-censorship tool, the FreeGate. All we users owe you.
As spsdth reported, Freegate is totally useless right now in Iran. "A tunnel" is slow and unstable, "F tunnel" shows a 1x1 gif image for any address.
Please consider this problem.
Regards

Areas other than China may not be able to use F mode. You may try the default Auto mode.
