Hm I have hotspot - enabled-address method with web proxy (transparent) and also in proxy there is rule for Deny using us as telnet and SMTP relay …
And now I just added PPP server on same interface (with another IP subnet and another ip pool for PPP users).
Well for now it was just look that is everything is fine , but (always some but 
) there is some problems:
So when i test this PPP and connect browsing web is working , mail , ICQ etc… everything is fine exept few things …
… ftp upload is not working … it start and then go slower … and then stop and after while it say that is finished , but on the other side on ftp this file is 0 bytes … (I was test active and passive mode - same results)
Also somethimes I cannot send mail … same thing outlook express is sending mail long time …
Then when I disconect and connect with browser via hotspot everything is work fine …
So I was think that maybe is problem that I use enabled-address Method,
maybe I need to use dhcp-pool method ?
Any idea or sugestions how to “fix” this problems is welcome …
