Re: Fw: [suse-security] Request of servers wins and servers dns, By VPN PPTP

Gentlemen, Good Night gentlemen, Favours the tips of the gentlemen I obtained, to make a Server VPN in SuSE with PPTP, already I obtain the VPN, only that when I receive the IP from creaks it specified in the VPN server, I do not obtain to make nothing, Therefore my request of ms-dns, ms-wins is DROPs for the FW, for Anti-spoofing, some of the gentlemen knows as I can decide this? In mine opitions.pptp, is with the options of ms-dns and ms-wins, is necessary? or the Client Vpn would assume this automatically?
