no http data when connecting using Huawei e5331 bb modem
Posted: Sat Oct 12, 2013 10:52 am
I have openvpn server on a Centos box, and have been connecting from numerous sources for many months. However, when I connect from a remote client using a Huawei e5331 broadband modem, I have problems accessing my ruby on rails server (http request doesnt get through). RoR server is on the same box as the oenvpn server.
I can use an earlier Huawei E585 modem and everything works fine.
With the E5331, openvpn connects perfectly, I can ping the server and I can log in over ssh and list directories etc.
But when I make a request from the client browser, I just get no response.
I look at the client end tunnel and I see the GET request going out
If I look at the tunnel on the server end, I see two HTTP frames received, then there is an Rtx request between the server and the tunnel ip address, then nothing. The GET request just never arrives. I am totally perplexed, but then I am not a network expert.
I recall having a similar problem with another Huawei modem a while ago, that would connect to one of my RoR sites via openvpn, but on the other the http just ground along and eventually froze. Seems like a similar but worse situation.
If anyone can help with ideas of things I could perhaps try or investigate I would be grateful because I am out of ideas.
