Thanx for that Tim,
I have got it sort-of working by following that.
0 D ;;; gateway.netcash.co.za
hotspot1 allow 0
1 D ;;; gateway.netcash.co.za
hotspot1 allow 0
2 D hotspot1 allow 0
3 D ;;; acssb.bankserv.co.za
hotspot1 allow 0
4 D ;;; 3dsecureprd.fnb.co.za
hotspot1 allow 0
5 D hotspot1 allow 0
6 D allow 0
7 X ;;; place hotspot rules here
allow 0
8 hotspot1 gateway.netcash.co.za 443 /vvonline/ccnetcash.asp allow 0
9 hotspot1 www.tns.radius.co.za /radiusmanager/buyias.php allow 0
The only problem remaining is that once the authorisation has been requested, the accept/decline does not get back to the Radius. It hangs on the Netcash page after 3d secure/verified by visa has been completed.
