Problems with Virtual Box NAT

[Cossack]

Hello everyone.
I'm having some problems with NAT on Vista Ultimate x64 , Virtual Box 2.2.4, Fedora 11 installed as a guest . I'm trying to make this thing work but without any success , ( VMware works as a charm and without any adjustments). I'm suspecting that some of VM ware drivers could conflict with Virtual box, but I can't uninstall VMware till I will be sure that it's causing problems. And what else I need to do to get NAT on my guest Fedora ( 8,11) and Ubuntu (9.04) ?

My exact problem : NAT doesn't work at all. During the installation on Vista Ultimate x64, VB created "Virtual Host-Only adapter" without any other options. Than I enabled NAT and selected adapter for guest connection .... Guest network interface captured correct tunes ( DHCP, domain name...etc ) but web is still not accessible for guest.

- I tried to use static protocol and use my host as a Gateway
- Marked vnat.exe as a "trusted" for the host firewall, disabled active armor in a BIOS
-Tried to modify rc.local in such way:

TUN=vbox0

IP=192.168.17.1

USERNAME=Cossack

tunctl -t $TUN -u $USERNAME

ifconfig $TUN up

ifconfig $TUN address $IP netmask 255.255.255.0

arp -Ds $IP $TUN pub

iptables -t nat -A POSTROUTING -j MASQUERADE

echo 1 > /proc/sys/net/ipv4/ip_forward

echo 1 > /proc/sys/net/ipv4/conf/$TUN/proxy_arp


I'm expecting to get internet on my Guest OS

Ok, well, in that case, did you check the VirtualBox FAQ for possible Firewall incompatibilities? There are some firewall software that just doesn't play nice with VB NAT.

As for the new adapter you got, that's got nothing to do with NAT. What you got is a virtual interface which you can configure through the VB global preferences. It's the Host-Only adapter that you can use to get a network between your VMs and your Host, totally separated from your physical network.
