when LAN users try to open the company website "www.website.com" -using UTM as explicit proxy- they get a web proxy error windows specifying "Invalid argument".
The site is in a complete exception list for everything and is hosted on an internal server that has the external pertinent ip forwarded via WAF.
http proxy log shows the error:
2014:08:19-11:58:44 astaro httpproxy[5590]: id="0002" severity="info" sys="SecureWeb" sub="http" name="web request blocked" action="block" method="GET" srcip="192.168.0.8" dstip="190.224.***.xx" user="" statuscode="502" cached="0" profile="REF_DefaultHTTPProfile (Default Web Filter Profile)" filteraction="REF_DefaultHTTPCFFAction (Default content filter action)" size="2501" request="0x124b67a0" url="www.domain.com/" exceptions="av,auth,content,url,ssl,certcheck,certdate,mime,cache,fileextension,size" error="Invalid argument" authtime="0" dnstime="226002" cattime="0" avscantime="0" fullreqtime="226625" device="0" auth="0"
then i disabled web proxy in IE (there is a packet filter rule in place for lan->internet*[web protocols]) and it works ok
what's going on?, why is it giving that fake error when it's working ok from the outside and from lan without proxy configured?
