The follow schemes.
Wi-Fi Client (notebook, workstation and etc) - RB411AHPON (AP Bridge, Sector 2400/65/15) - LAN - MT x86 (pppoe-aggregator, hotspot, dhcp, traffic flow, shaper, Radius) - RB493 (NAT, Firewall, WAN-Interface) - the Internet.
Client address from dhcp receives, authorization for the radius of billing, billing accounting traffic - is very well.
If the client is authenticated through the built-in account in mikrotik hotspot "admin", then the billing did not account the traffic, but all services are available.
If a customer raises a pppoe-connection, the Internet works as expected, all protocols are available.
If authorisation occurs through the Hotspot-Radius, the client receives only the port 80. But no icq, no skype, etc. services not available, using a different 80-second port is not working. Sometimes Skype is starting. I understand that the hotspot creates its own proxy-server. how can to made available the use of an all range of ports in the hotspot, another then port 80?
P.S. sorry for my bad english.
