VPN through PIX then through ISA2004
Posted on 2006-07-13
I would like to configure a VPN tunnel inside a VPN tunnel. the facts
I've just solved a problem regarding the Cisco remote access vpn client connectiong to ciscoASA5510 so now it works , I get access to pix and I can see now the external Isa2004 netwrok I would like to establish another vpn if I would like to gain access further into internal network , I 've setup isa as a vpn server using pptp and radius, it works perfectly if not using cisco vpn,
but if I connect from internet and use cisco vpn then inistiate pptp connection to isa I will get connected but no traffic is going on, since I can not get dns settings , I can not ping inside network , it seems that cisco vpn tunnel is not allowing me ,
my question is how should I tell cisco to allow trafic through new tunnel?
I tried split tunniling and created an exemption network which will be exempted from the cisco vpn tunnel ,and this way everything works but is this secure in thes respect? or is there other way to make a vpn tunnel inside a tunnel to work?
thanks in advance
