SureBackup Masquerade Question

Post by CaterhamKing »

Hi,

With a site that has a class A network configured, 10.x.x.x / 255.0.0.0, I would like to know what to configure as the masquerade address in SureBackup? I have tried a number of different networks, all give this error "Specified mask parameter is invalid (MasqueradeNetworkAddress & Mask) != MasqueradeNetworkAddress"

10.0 does work, which is then converted to 10.B.C.D. Not sure this would be right though. Any feedback appreciated.

If it’s A class network, why not just to change the first IP block, then?

Production: 10.x.x.x / 255.0.0.0
Masquerade: 11.x.x.x / 255.0.0.0

Thanks.

I agree, but that is what gave the error: Specified mask parameter is invalid (MasqueradeNetworkAddress & Mask) != MasqueradeNetworkAddress

You can then OK that, and go back to the same screen asking for Masquerade address :(

I know it's not related to Veeam, but any chance you can shrink that subnet? an 8 bit subnet has also huge problems with broadcasts and ARP tables... do you really need to keep it so large?

(MasqueradeNetworkAddress & Mask) != MasqueradeNetworkAddress
Strange error, indeed, since even the simple math suggests that everything is specified correctly:
Masquerade Address: 11.0.0.0
Netmask: 255.0.0.0
Masquerade Address & Netmask: 11.0.0.0
Binary math:

Code: Select all

00001011.00000000.00000000.00000000
&
11111111.00000000.00000000.00000000
=
00001011.00000000.00000000.00000000
So, it's a high time you opened a ticket with our support team, letting them investigate it directly. Thanks.

Actually, 11.0.0.0 does work. You sir are a genius!

I’m wondering whether you have taken some additional steps to make it work, or you’ve just specified the aforesaid parameters and everything went, as expected. Thanks.

No, just the usual steps. I have no idea what we did first time round, but as soon as I edited the lab and put this masquerade in it worked :) Honestly, I think it was our fault.
