Hello there,<br>
<br>
I've got a connection problem using the Shrewsoft VPN client and a<br>
Netscreen 5GT using UMTS (surf stick, Vodafone Germany).<br>
<br>
There is no connection problem in general (the VPN connection works<br>
without problems using DSL with different PCs), only when the client<br>
tries to establish a connection via UMTS (Vodafone Germany).<br>
<br>
The client mailed me the log/trace of his Shrewsoft client. On the<br>
Netscreen (VPN gateway) there is no entry in the log, so I assume that<br>
the Shrewsoft client don't even reach the Netscreen. Does anybody can<br>
help me with that, maybe with interpreting the following trace? Maybe<br>
it's a problem with Vodafone blocking the needed ports? Thanks!<br>
<br>
In the following trace, I replaced the client IP address with<br>
xx.xx.xx.xx, the VPN Gateway IP address with yy.yy.yy.yy.<br>
<br>

Hi Johan,<br>
<br>
The trace shows that Shrew did not receive a response to the packet that it sent to the gateway. Since you indicate that the gateway logs show nothing, it does appear that the packets may be blocked.<br>
<br>
There have been a few other posts on the list about people having problems with UMTS connections, but as far as I know, there's not been any resolution. This might mean that people have solved the problem and not written back, but it also might mean they've given up.<br>
<br></blockquote><div>Also some UMTS operator block VPN Protocol.... <br></div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"><div><div></div>
