First-time experience with this scenario on an active site.
25 users mix of desktops and laptops.
UCM 6102 totally locked down from Wan
Sonicwall managed by IT company controlling all rules
No Vlans voice and data on one network and one set of cabling pc plug into the back of the phone.
cant create a rule on the LAN to restrict t traffic to the PABX cause the phones need to reach the PABX.
Sure we could do a reserved range for the phones then allow only that range local to the PABX.
The only time this login attempts stopped is when they closed and went home for the day. Suspect a user pc is infected and creating a path back in.
Think this is interesting as lots of companies want one simple network. Just thought I with share it since its the first time This has happened and we have hundreds of posts on remote extensions and locking down the wan connections securing the PABX on the Wan…
I used to insist on managed switches and VLANs until I followed the advice on a Spiceworks discussion why create complexity on a small network VLANs do nothing. Today it seems I may be paying the price of following that post discussion.
Hopefully, we fix it in the morning as each who logs on, we will monitor traffic and see what happens.
like to hear how forum members have dealt with this has it only a matter of time before you encounter this if you already have not.
