Thanks for your answer, i know the link but i thought it is for wifi an i thought it is to hard for me to adapt it.
In the meantime i had the linsys client running on my local lan and it was working but not from outside.
In a firewall howto i found that some ports must be open:
* UDP-Port 500
* UDP-Port 10000
* IP-Protocol 50 (ESP)
* TCP-Port, der für IPsec/TCP konfiguriert ist (Port 10000)
* NAT-T (Standards-Based NAT Transparency) Port 4500
Maybe there are people who can give me info or like to work out it with me ?
regards
