Using ath0 as bridge in VMware... or almost10 Oct 2006
Well I couldn’t make my Atheros (ath0) work as a bridged network with VMware… but I made a workaround which I want to share with you guys. Anyways I’ll have it documented if I cant remember what I did later on. I have installed VMware on my Ubuntu laptop and a edgy-alternative (server) as a guest OS within VMware. The way I did this was making my laptop into a router between the “VMware host only” net and my wireless net.
You need to have configured a host only network for your VMware machines, mine is called
vmnet1 and is using the network:
My laptop has the following ip’s:
wireless: ath0 192.168.20.197 (provided by DHCP) wired: eth0 * (not used in this example) VMware net: vmnet1 192.168.154.1 (static) gateway: default 192.168.20.1
My Ubuntu edgy server has the following ip’s:
wired: eth0 192.168.154.2 (static)
On my laptop I have made a script that does the following:
INTERNAL=vmnet1 EXTERNAL=ath0 # Enable router functionality echo 1 > /proc/sys/net/ipv4/ip_forward # Enabling SNAT (MASQUERADE) functionality on $EXTERNAL iptables -t nat -A POSTROUTING -o $EXTERNAL -j MASQUERADE
All my rules are set to accept as default, if yours are not you might want to add something like this:
iptables -A FORWARD -i $EXTERNAL -o $INTERNAL -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A FORWARD -i $INTERNAL -o $EXTERNAL -j ACCEPT
On my VMware guest I have configured
eth0 to have the static ipadress
192.168.154.2 and to use
192.168.154.1 as default gateway. The way you set this up depends on you guest OS, but you can also do this manually with:
INTERNAL=eth0 ip a add dev $INTERNAL 192.168.154.2/24 ip link set $INTERNAL up route add default gw 192.168.154.1
Now test by pinging you host’s gateway (my laptop):
Note: You propably want to set you guest OS to be able to use a DNS server.
