 |
|
hello!
we have a webserver running with multiple ip-addresses on the same interface in different subnets. of course they do have different routes with different metric, but is there any way to make that via conf.d/net?
current setting:
/etc/conf.d/net:
| Code: | config_eth0=( "a.b.c.196 netmask 255.255.255.248 brd a.b.c.199"
"d.e.f.24 netmask 255.255.255.224 brd d.e.f.31" )
routes_eth0=( "default gw a.b.c.193" ) |
/etc/conf.d/local.start
| Code: | | route add default gw d.e.f.1 metric 5 |
i searched a lot but the routes feature of conf.d/net is not well documented for alias-interfaces.
thanks in advance,
andy

Should work |
_Why_ should it work?
I have a similar problem where I have a server on a network which needs two routes defining.
There is a default gateway, which goes outside the LAN, and a vpn router for internal site to site traffic.
netstat -rn gives me:
| Code: | hydra01 ~ # netstat -rn
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
192.168.0.0 192.168.1.200 255.255.0.0 UG 0 0 0 eth0
127.0.0.0 127.0.0.1 255.0.0.0 UG 0 0 0 lo
0.0.0.0 192.168.1.202 0.0.0.0 UG 0 0 0 eth0
|
How can I define this in conf.d/net?
Cheers,

afaik it should look this:
| Code: | routes_eth0=(
"default gw 192.168.1.202"
"-net 192.168.0.0/24 gw 192.168.1.200") |

You, sir, are a star.
With a minor modification that looks kinda like this:
| Code: | config_eth0=( "192.168.1.10 netmask 255.255.255.0 broadcast 192.168.1.255" )
routes_eth0=(
"default gw 192.168.1.202"
"-net 192.168.0.0/16 gw 192.168.1.200"
"-net 10.0.0.0/8 gw 192.168.1.200"
"-net 128.0.0.0/8 gw 192.168.1.200"
)

My routes are set as needed to access out VPN'd subnets (including two client networks)
