Strange issue with remote offices IP address.
Posted on 2013-06-06
I have a strange issue. Client with 2 remote offices. Changed PC out for accounting which included ADP time clock function. Access to remote time clocks stopped after I upgraded PC. Checked IP from other PCs and the remote time clock IPs still don't respond. No response from remote time clocks on the main network (100.x)
No changes at all to the ASA5520 routers that manage T1 and cable modem inputs. No changes to routers that support T1s. ADP was remoted in to the new PC and the tech couldn't understand VPN and the fact that main office is 100.x and remote offices were 101.x and 102.x i am suspecting that he did something to the time clocks that has caused issue.
So all links are up...everything else is connected and pings fine. When I ping remote time clock from main office its a no go. When I ping from an onsite computer at the remote site, I get a response.
I am reasonably good with understanding branch office VPN but am really stumped on this. What might have happened at the main network to have those IPs blocked? (we rebooted routers) or...what might have been programmed by ADP tech on their ATS240 time clocks in the IP config to have them not respond to the main office IP range?
Not only will you get points for answering this but you will have my undying gratitude.
