Hello,
this is probably a FAQ and/or I'm to tired, but I'd be pleased
if anyone can tell me what I do wrong :
I have a box with two interfaces, one connected to my lan
(172.16. ), one to a test-box (192.168.1.1) :
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM>
ether xxx
inet 172.16.1.240 netmask 0xffffff00 broadcast 172.16.1.255
media: Ethernet autoselect (1000baseTX <full-duplex>)
status: active
em1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM>
ether xxx
inet 192.168.1.254 netmask 0xffffff00 broadcast 192.168.1.255
media: Ethernet autoselect (1000baseTX <full-duplex>)
status: active
I enable ip.forwarding :
# sysctl net.inet.ip.forwarding
net.inet.ip.forwarding: 1
And this is my routing table :
Internet:
Destination Gateway Flags Refs Use Netif Expire
default 172.16.1.254 UGS 0 20 em0
127.0.0.1 127.0.0.1 UH 0 0 lo0
172.16.1.0/24 link#3 UC 0 0 em0
172.16.1.6 xxxxxxxxxxxxxxxxx UHLW 1 87 em0 1194
172.16.1.230 xxxxxxxxxxxxxxxxx UHLW 1 286 em0 572
172.16.1.240 xxxxxxxxxxxxxxxxx UHLW 1 0 lo0
172.16.1.254 xxxxxxxxxxxxxxxxx UHLW 2 0 em0 487
192.168.1.0/24 link#4 UC 0 0 em1
192.168.1.1 xxxxxxxxxxxxxxxxx UHLW 1 2 em1 616
192.168.1.254 xxxxxxxxxxxxxxxxx UHLW 1 0 lo0
For this I added to rc.conf :
static_routes="test lan"
route_test="-net 192.168.1.0/24 192.168.1.254"
route_lan="-net 172.16.1.0/24 172.16.1.240"
Now from my test-box 192.168.1.1 I can reach (of course) 192.168.1.254,
I can reach 172.16.1.240, but no other IP.
What do I wrong, please!?
Thank you very much for any help in advance.
Best regards, Arno
