So far so good. Enabled Portscan Detection this works now as same as V4.x , did a portscan with grc.com & scan.sygate.com both sended an e-mail warning. But still tells that port 25 & 443 are open... Enabled DoS/Flood Protection, did the same portscans and now ALL ports are being seen as "stealth"!!! Whooopie. Unfortanutely I can't check SIP cause I don't use this. So finally checked the CPU usage max,. load was 40% so my celllie is doing fine. Also imported my license for ASL and is also imported succesfully. As far as I can judge everything is working fine and got until now no bad impression of it. Keep up tha good work ASL-crew. [btw first post LoL]
