I have some strange website access issue. On work, I can access the part of the website but few pages show forbidden access and can't access them. However, I can access those pages from home or from smart phone, as long as I am not on the work network.
Steps I have taken so far but did not resolve the issue:
total 5 PCs, all PCs, can't access the same pages, but can access other pages, including home page. from home or if I use Cell Data can access those pages. Do you think could be a problem with the modem (ISP). I am using ISP cable modem, which connects to USG router and to switch (netgear 24 port). What else I can do to resolve the issue, should I check with ISP or any other step I can do before contacting them?
Thanks in advance.
Steps I have taken so far but did not resolve the issue:
- cleared the browser cache. and also used incognito window
- installed clean windows on one PC, even that PC couldn't access those pages
- flushed dns, (ipconfig /flushdns)
- replaced the router from TPlink to ubiquiti usg
