 Posted: Tue May 16, 2006 3:12 pm Post subject: gentoo & vmware dual nics in non-promiscuous mode [SOLVE |
 |
|
Everytime we use vmware after a standard install we will be using the box nic in promiscuous mode soon as we start vmware network.
My question is simple.
Can we use another existent different phisical nic to use it with vmware ?
In other words with regular use of vmware once we setup and start the vmware network vmware will create a virtual nic that will use the box default phisical nic. Lets say eth0.
ie: vmware-virtual-nic ---> <linked> eth0 --> cable --> router -- > wan/lan
my box has 3 physical nics (eth0 eth1 eth2 )
gentoo uses eth0 with a cable that goes to the router and then
gentoo --> eth0 --> router --> wan/lan
what i want is to make vmware to use eth1 with a cable that goes to the router and then wan/lan.
---------| GENTOO --> ETH0 --> CABLE --> ROUTER --> WAN/LAN
BOX -- |
---------| VMWARE --> GENTOO --> ETH1 --> ANOTHER CABLE --> ROUTER --> WAN/LAN
(eth0 and eth1 will have different ips)
im sure this can be done ...and im looking for some tips about it

ok so no replies yet... ehehe.
Lets divide things in 2 steps.
1: setup 2 nics in gentoo with 2 diferent ips
2: setup vmware to use eth1
I belive that the vmware parte is the easiest; so for now i just need some tips to setup the different 2 nics .
I have created the respective init script for eth1 and even added another ip/setting in /etc/conf.d/net
however it fails here:
| Code: | # /etc/init.d/net.eth1 start
* Starting eth1
* Bringing up eth1
* <***.***.***.***> [ ok ]
* Adding routes
* default gw <***.***.***.***> ... [ !! ] |
It fails when looking for the gateway. ( i have specified the gateway="eth1/<ip>" ) in conf.d/net because it seems unable to use the same ip/gateway that eth0 uses.
So i tested it by adding another ip there as if i had another router/gateway and it worked.
Unless i can work this around in with gentoo.... the other fast and possible way is to had another router to the network to be setup between my box and the main router. ( this option does suck a bit )
and that would be like this:
---------| GENTOO --> ETH0 --> CABLE --> MAIN-ROUTER --> WAN/LAN
BOX -- |
---------| VMWARE --> GENTOO --> ETH1 --> ANOTHER CABLE --> ROUTER2/WITH-DIFFERENT-GATEWAY --> MAIN-ROUTER --> WAN/LAN
For some reason both nics (eth0 & eth1) seem to fail to use the same gateway. . Is it suppose to be like this ?

Depends. Please post both IPs of eth0 and eth1 and their netmasks. |

AFAIK you can't have two nics on the same logical network connected two different physical networks...
I suggest bring eth1 up but without any ip configuration, then bridge it with vmware nic (through vmware-config.pl), then in vmware you'll end up with only one interface which can be setup same as eth0 in gentoo (it won't be complaining)
This way you can use eth0 in gentoo and eth1 in vmware.
If you'd like to use eth1 in gentoo you could nat it in vmware...

currently i have it working flawlessly 
---------| GENTOO --> ETH0 --> CABLE --> ROUTER --> WAN/LAN
BOX -- |
---------| VMWARE --> GENTOO --> ETH1 --> ANOTHER CABLE --> ROUTER --> WAN/LAN
example of /etc/conf.d/net
| Code: | config_eth0=( "192.168.0.2 netmask 255.255.255.0 brd 192.168.0.255" )
routes_eth0=( "default gw 192.168.0.1" )
config_eth1=( "192.168.0.3 netmask 255.255.255.0 brd 192.168.0.255" )
routes_eth1=( "default gw 192.168.0.1" ) |
this topic is solved.
