I'm trying to upgrade my firewall and seem to be stuck getting a default
route out to the rest of the world. The firewalls internal address is
10.0.0.10 which is connected to a mutli-homed host on 10.0.0.0. &
192.168.0.0. below is the routing table and interface info for the host.
Everything works fine at this point.
Setup looks like this:
broadband -> firewall -> multi-homed host -> switch -> internal network
Routing Table: IPv4
Destination Gateway Flags Ref Use Interface
-------------------- -------------------- ----- ----- ---------- ---------
default 10.0.0.10 UG 2 1 rge0
10.0.0.0 10.0.0.1 U 5 10372 rge0
127.0.0.1 127.0.0.1 UH 2 312 lo0
192.168.0.0 192.168.0.1 U 9 8804063 rge1
rge0: flags=1100943<UP,BROADCAST,RUNNING,PROMISC,MULTICAST,ROUTER,IPv4>
mtu 1500 index 2
inet 10.0.0.1 netmask ffffff00 broadcast 10.0.0.255
rge1: flags=1100843<UP,BROADCAST,RUNNING,MULTICAST,ROUTER,IPv4> mtu 1500
index 3
inet 192.168.0.1 netmask ffffff00 broadcast 192.168.0.255
So I setup the new firewall at an internal address of 10.0.0.20,
recreate my rules, setup the wan port to be identical to the old
firewall. Check, double check, triple check... yep everything is setup
exactly the same except for the internal address of 10.0.0.20
Ok, so now I turn off the broadband modem, shutdown the host, replace
the firewall. Turn on the modem, turn on the firewall, boot the host and
login. I can ping any address on both internal networks, the firewall
and wan port but nothing beyond. Looking at the new routing table the
24.0.0.0 seems to be wrong to me.
Routing Table: IPv4
Destination Gateway Flags Ref Use Interface
-------------------- -------------------- ----- ----- ---------- ---------
10.0.0.0 10.0.0.1 U 3 6 rge0
24.0.0.0 10.0.0.20 UG 1 0 rge0
127.0.0.1 127.0.0.1 UH 2 12 lo0
192.168.0.0 192.168.0.1 U 4 24 rge1
so I try:
route delete 24.0.0.0 10.0.0.20
route add default 10.0.0.20 and get network unreachable...
How do I get my default route back?
