I have gentoo linux running inside a VirtualBox Windows 10 host, which used to work until recently.
Basically no matter what protocol I try to use, I get that the network is unreachable, for any public networks, except for the fact that DNS lookups, and ping work. Windows firewall is completely disabled. How can I get 'internet access' and such working?
I have 5 Vlans on my network, so I've set which one should be used using:
VBoxManage modifyvm "Gentoo" --natbindip1 10.XXX.XXX.XXX which appears to have done the trick, otherwise nothing will work at all.
Also I've had to do
VBoxManage modifyvm "Gentoo" --natdnshostresolver1 on otherwise DNS resolution doesn't work, even when I set the correct DNS servers.
If I change
VBoxManage modifyvm "Gentoo" --natdnshostresolver1 off then DNS lookups don't work, however I can still ping out but wget (as an example) still gets
Network is unreachable.
The error I get when trying to access any kind of network resource is:
Connecting to www.mirrorservice.org|126.96.36.199|:80... failed: Network is unreachable.
DNS / dhcp appears to be working correctly, as it sets itself:
tim@vbox ~ $ cat /etc/resolv.conf # Generated by dhcpcd from enp0s3.dhcp # /etc/resolv.conf.head can replace this line nameserver 10.0.2.3 # /etc/resolv.conf.tail can replace this line tim@vbox ~ $ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 10.0.2.2 0.0.0.0 UG 2 0 0 enp0s3 10.0.2.0 0.0.0.0 255.255.255.0 U 2 0 0 enp0s3
As an added oddity, if I instead bind to a different vlan, which DOES use a proxy server, and setup the proxy server in the VM - this then has full connectivity to the internet, as expected. It's almost as if when binding to some of the vlan's, not all traffic is passed over that vlan.
I can't use network bridging, as there is no default VLAN set, and I don't want to try and setup on another VLAN because of office politics ;)
