bis over wifi prohibited

[agold2]

Hi all,
I have a small problem - "BIS over wifi" is not officially supported by carriers in Russia. It's worked some time ago but not now.
But the same time, a very small qnt of bb users still gets it working. For me it's mean, that prohibition is not on the RIM servers, but in carrier's.

So, the question, is it possible to solve this?

Of course, I have BB plan and working BIS-B over mobile network.

Some additional info:

In the HRT I have 4 lines:
GPRS RU
WI-FI [60]
GPRS RU
GPRS RU

In the WI-FI [60] I have 4 lines:
rcp.eu.blackberry.com:443
rcp.eu.blackberry.com:443
93.186.25.40:443
193.109.81.88:443

In the SB section I have 2 WIFI lines:
Brower config with GW: IP://206.51.26.197:19989:19998
and WPTCP with GW: IP://10.1.26.207:19781;19780 (if WIFI is not connected, this field is blank)

In the WIFI Diagnostic I have no IP addresses yet and red cross

In the engineering menu, TMM Tunnel Engineering screen I have 2 tunnels:
1. 3GPP:blackberry.net<10.250.31.198>
2. WLAN <192.168.1.100> (it's IP address which bb got from wifi router via dhcp)

Any help will be appreciate!

Regards,
Andrey
