The connection to the Computer was just to test the VPN Server. And there the connection is working. Normally there is just the WRT54GL VPN Server and the WRT54GL VPN Client. Because of that I allow just one IP 126.96.36.199-100 at VPN remote IP on server side! I'm not pretty sure about the config of the red and green boxes. When I sit on Client-side: -> lets say I got Ip 100.100.100.100 ...and I make some pings: ping www.google.com ping 188.8.131.52 ping 184.108.40.206 When "VPN Client" is not activated ping to google is normal. When "VPN Client" is activated ping to google is 10 times normal than 20 drops, than 5normal, 10 drops, 15 normal, 15 drops for example.... ping to 200.200... is never working! I thought I was able to reach one time http://220.127.116.11, but maybe it was a mirage.
