surebackup applicae IP issue

[kte]

We are configuring sure backup in a 10.100.1.x /255.255.254.0 environment, but the masking network in the virtual lab appliance is always a class B (172.20.x.x) in stead of /23
And if we take 10.100.2.254 /255.255.254.0 the masking IP can be 172.20.2.x.
But all the main production servers are a 10.100.1.x /255.255.254.0 range, is this a bug or another reason.
Can we modify this on the Linux appliance directly

Hi, Koen. Could elaborate on your issue a little bit? I'm asking since I’ve just tried to specify given IP/mask and returned masquerade address was 10.255.2.x, as expected. Thanks.

[kte]

it seem it is just that range that is not working 10.100.0.x /255.255.254.0 it only proposes 172.20.x.x. So it seems it is not calculating the correct network for a 10.100.0 , the zer cause the issue
But if we use 10.100.2.x/255.255.254.0 we can use 172.20.2.x which is good. But all the main production servers are in the 10.100.0.x range so I can't do surebackup or restore AD, SQL, exchnage 2007 and uair
support case number is 00428818

Hmm. seems to be a bug, indeed; though, based on quick test I’ve done with v7, it appears to be fixed there. Anyway, let’s wait and see what support team says about it. Thanks.

[kte]

Got support they said to try with 10.100.0.x /255.255.254.0 masked as 172.20.x.x.
It seems to work on 1 machine I tested, but I still need to test all the routing between the other subnets.
And create an actual AD / SQL /sharepoint application group and test all the functions

[veremin]

Kindly keep us updated about the results you get. Anyway, as mentioned, this bug seems to be fixed in the upcoming version of VB&R; so, stay tuned. Thanks.

Hi, Koen. Just checked this scenario in version 7 and everything appears to work as expected. So, it might be worth updating. Thanks.

Any ideaa how many nics the proxy can have in v7 because in v 6.5 it where only 3 nics for the isolated networks

[Vitaliy S.]

Do you mean the proxy appliance? Just upgrade its virtual hardware version to the latest available, and you'll have more than 3 NICs to use in the setup.

[kte]

ok so I need a version 7 or 9 ??

[Vitaliy S.]

Doesn't matter, as both options will give you an ability to use more NICs.

[kte]

because in 6.5 , no virtuall HW upgrade it said that we need to contact support to add more nics, but this means the virtual HW upgrade?

[Gostev]

Yes.

[veremin]

Actually, this trick, as well as, many other interesting ones, is mentioned in 6.5 Surebackup Configuration Guide written by Ben Milligan; so, it might be worth taking a look.

You can only add up to 4 networks here to the virtual lab, as this is the limit for VM Hardware version 4 of VMware (VI3). You can however increase this ability, by updating the virtual machine to version 7/8 hardware version of VMware. Simply right click on the virtual lab virtual machine in vSphere client after creation, and select Upgrade Virtual Hardware. This will allow you to add additional network connections to the lab, up to 10.

Thanks.

After upgrading to version 7 , I still have the issue with the ip masquerading and I can't define any isolated IP vlan id's , because when I add a nic all become the same

[veremin]

As mentioned, I’ve already tried several tests with version 7 and the situation with vLab proposing only B-class network shouldn’t be the case any longer:



So, if you experience different behaviour, it might be worth contacting our support team and letting them investigate it directly. Thanks.

As to the VLAN issue, it stands to reason to recreate previously-used Virtual Lab and see whether you’re able to specify correct VLAN in the settings of newly-created Virtual Lab. Thanks.

[kte]

If i put 10.255.0.x is says 10.255.x.x but I'll change the masquerading IP

I recreate my lab and the vlan issues stays in mapped networks if I add a second network all network have the same vlan

[veremin]

Hmm, 10.255.0.x is an IP address, and what is the mask you’re trying to specify? 255.255.254.0? Thanks.

[kte]

OK the applicance seems to be working

10.255.0.x is an IP address, and what is the mask you’re trying to specify? 255.255.254.0

correct , then I have the full rang
I changed it to use 10.255.2.x now

Glad to hear that you’ve finally solved your issue. Should any additional questions arise, don’t hesitate to let us know. Thanks.
