Network Configuration not accepting IP Block

mfleming07 asked
Last Modified: 2013-11-16
  I am trying to switch to a new Internet connection on our watchguard firebox.
1. can I just edit the current configuration with the new Ip's and upload it to the firebox?
2. when I try to enter the new IP lan Block in Network Configuration it turns red and will not accept the block 64.X.X.X/29
I don't think it likes the subnet of /29

Thank You

Watch Question

may be your trying to enter ipaddress/29, not network_address/29?


I'm typing the Ip assignments that they gave me:
Customer LAN Block: 64.X.X.X/29    if I put a /24 it would accept it. I tried a fresh config, but the firebox still will not accept the block

can you please write your netblock here. you can mask first and second octets, but at lease leave the last one unhided


customer LAN Block: 64.X.X152/29
Customer Gateway: 64.X.X.153
Usable Range: 64.X.X.154 - 64.X.X.158
Customer Subnet:

Ok the netblock itself is correct.
Are you trying to put an ip address on your otgoing interface
or you are trying to create just network object ?


Trying to enter it into the External outgoing Firewall interface

the 152/29 is a network, you your first free ip of the interface is 154/29 and your gw is 153/29


OK, so I need to put a working Ip address 154/29 in the config. I though I needed to put the lan block that they assigned me. I will give that a try tonight when I can bring the line down.

>> customer LAN Block: 64.X.X152/29
>> Customer Gateway: 64.X.X.153
>> Usable Range: 64.X.X.154 - 64.X.X.158
>> Customer Subnet:

You cannot put the subnet IP in the WG GUI; you can try putting as IP on external [or any subnet IP like] and can notice that you would receive error; as your first usable IP is .154 put this or any which you think should be the external IP of your box and it would get accepted.

Thank you.


Thanks for the help From_EXP....I got everything setup....NAT'd and up and running with the first useable IP address. Watchguards manuals and Knowledge base are not very helpful.

good luck mfleming07!
