How to change the SSLVPN IP Pool range on a SonicWall

Have just began working at a site. While documenting and auditing IP ranges, I observed that the SonicWALL TZ-210 has been configured to dole out IPs to incoming SSL VPN clients in the same range as that used for printers.

I have attempted to edit this, however the changes do not "take", After changing 192.168.10.90 and 192.168.10.99 to 192.168.10.20 and 192.168.10.29, I click OK.  The "Ready" changes to "please wait" for a second and the dialog box closes as expected, but the setting don't change.

Any SonicWALL experts here have any ideas?

Is any part of the new ip address range you entered already used in some other address object?

Check the setting under firewall => address objects

Would you are seeing would be typical of this.

Only possible clash is the "Lan primary subnet", 192.168.10.0 255.255.255.0. Can't really get rid of that.

You need to make sure that none of the addresses in the  "old" range are in use when you try to make the change. You can go under SSLVPN to release them.

Definitely were none in use. Although we have a block of 10, the VPN is hardly ever used on this site.

I just realized that your post of the SSLVPN pool above is not really that, but rather just an address object that I suspect is used to control what activities are permitted when connected via the SSLVPN.

Go to SSLVPN -> Client Settings and make the change there for NetExtender Start IP and NetExtender End IP.

If that works for you then find out what the Address Object is used to control as you might also need to change that as well.

I ended up just beginning again. Deleted the SSLVPN setup, creating a new IP range, rules etc. I think there must have been an easier way.

Didn't really work, but was a reasonable thing to check.
