trying to call external web service to determine VPN access

thanks for your help guys and apologies for the delay in replying (I've been away).

I have changed my web server to email me when it receives a request and although it seems to be going through the AAA server step, the website is not being contacted -

2014-10-20 09:26:54    Following rule 'Android' from item 'Client OS' to item 'Check MAC address'
2014-10-20 09:26:54    HTTP agent: ENTER Function executeInstance
2014-10-20 09:26:54    HTTP module: setHttpServerCfg(): server: /Common/check_MAC_address
2014-10-20 09:26:54    HTTP agent: LEAVE Function executeInstance
2014-10-20 09:26:54    Executed agent '/Common/nbi_policy_act_http_auth_ag', return value 0
2014-10-20 09:26:54    Following rule 'fallback' from item 'Check MAC address' to ending 'Deny'

is there a way of turning on a more detailed log level or something to find out what's going on? I've already removed the mac addresss element to turn the http request into something that should just work.

I'm using a custom post. I've set -

start URI=http://website.fq.dn (although I believe this field can be blank? tried both)

form action=http://website.fq.dn/infoserv/cgi-bin/computing/database/hardware/vpn/MacValid.asp?MacAddress=testing

Login detection=specific string in response Match value=TRUE (the text my website returns) Number of redirects=0 (although tried 10) Content type=URL encoded UTF-8

and nothing for the rest.

any ideas? thanks again.
