        Probwai da si wzemesh primerno kernel-a direktno ot ASP Linux, tam go ima po 
default, ppp-to syshto e podgotweno, abe ASP=RedHat + razni takiwa, 100%(99 
pone) sywmestimo. Po dokumentaciq PPTP polzwa GRE. 2 GRE tunela mejdu 2 IP-ta 
ne moje da se prawqt (po nqkakyw doc). Towa za discarded duplicate packet go 
dawa i ako se probwash ot lokalnata mashina da se zakachish kym neq s PPTP. 
Moje bi problema e che maskirash, a GRE-to malko trudno se maskira i... 
obyrni wnimanie na towa kak mashinata wyrzwashta se natam razbira routing-a 
prez 1-q i 2-q VPN. GRE tunel prez drug GRE tunel wyrwi - nqma principen 
problem oswen s obshiq razmer na paketa... Probwai 1-wo ot GW da se swyrjesh 
s drugata mashina za 2-q VPN... dai malko poweche opisanie na postanowkata.
        Za kernel-a... probwai malko po-nowichyk pone, toz ima 1-2 bug-a tochno w 
networking koda pokrai GRE/PPTP... (ako ne gresha w spomenite si)
