any recommendation for roaming ISPs (no NAT , ipsec , ssh pptp friendly).

[Boris shtrasman]

Hi,

I'm searching for a "roaming ISP" preferred using HSDPA or equivalent but not a
must.
I wish to be able to take my laptop and work for any urban area in IL
(Non GushDan areas), already checked few ISPs but they failed to
answer my needs (Pelehone & Cellcom):

Pelephone wasn't able to hold ipsec sessions, Cellcom provided me an
awful customer service (perhaps It's just my luck).

* The most important is to get not natted ip:
I need to be able to do ipsec + l2tp connections and lots of udp based
communication (zrtp/ srtp and plain old rtp).

* Most of the traffic is encrypted and going to a few selected servers
located in europe, it ain't a fixed rate (but not more then 1Gb per
day tops):
inner communication is :
A. rdp + vnc communication (as a client).
B. VoIP : sip + [zs]rtp heavy use  ~8 hours of talks on a daily basis and more.
C. version control (svn) : not more then 10mbs per day

I don't care about DPI , and privacy issues, but I do care about using
encrypted data transfer (as I use vpns ).

* preferred small delays but this is not a must - at least : download
rate  256 kbps  and upload 16 kbps.
(Kilo Byte)

* should support linux and windows without custom applications - I
must be able to communicate to the device using some public documented
way:
wvdial , mannual AT commands a kernel module already existing in the
kernel etc .. .
custom app for windows / linux is a big no-no for me.

Could anyone recommend something ?
