Hi all
I've searched the mail archive but could'nt find exactly what I needed.
Here it goes:
System config:
FreeBSD 3.3-STABLE
2 networks cards :3COM XL EtherExpress 905b
NATD for firewall(simple)
Stronghold web server
I've got *some* Linux experience, but very little with FreeBSD.
I've been trying to ad an IP address to my external card. So I cant use
that IP for a Virtual Host on Stronghold. Here's the exact syntax used in
rc.conf for both cards:
ifconfig_xl0="inet 192.168.1.1 netmask 255.255.255.0"
ifconfig_xl1="inet 207.236.242.12 netmask 255.255.255.240"
ifconfig_xl1_alias0="inet 207.236.242.5 netmask 0xffffffff0"
It seem to be ok, when I do "ifconfig xl1" I get:
xl1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 207.236.242.12 netmask 0xfffffff0 broadcast 207.236.242.15
inet 207.236.242.5 netmask 0xfffffff0 broadcast 207.236.242.15
ether 00:50:04:e1:a2:1e
media: 100baseTX <half-duplex>
supported media: autoselect 100baseTX <full-duplex> 100baseTX
<half-duplex> 100baseTX
10baseT/UTP <full-duplex> 10baseT/UTP <half-duplex> 10baseT/UTP
When i do a "netstat -rn -finet" I get:
Routing tables
Internet:
Destination Gateway Flags Refs Use Netif Expire
default 207.236.242.1 UGSc 6 43242 xl1
127.0.0.1 127.0.0.1 UH 0 0 lo0
192.168.1 link#1 UC 0 0 xl0
192.168.1.22 0:60:97:b5:97:30 UHLW 1 224 xl0 971
207.236.242/28 link#2 UC 0 0 xl1
207.236.242.1 0:10:7b:b3:cf:5b UHLW 7 0 xl1 183
207.236.242.8 0:50:e4:90:87:48 UHLW 0 430 xl1 1073
207.236.242.12 0:50:4:e1:a2:1e UHLW 0 20 lo0
But this is the first time I'm looking at routing tables....
When I ping the IP's locally I get no answer from my alias IP. But I do get
one when I ping it from inside my network. Which makes me think that it may
be a NATD problem. Do I have to declare my IP alias?
If so what is the syntax?
Here's a snipet from my rc.firewall
oif="xl1"
onet="207.236.242.0"
omask="255.255.255.240"
oip="207.236.242.12"
