Small website for our company is visible from every location except from computers in our office.
Ive ruled out everything I can think of, including :
Firewall. m0m0wall, very basic straightforward setup. I want to remove it and test, but powers above me say no, firewall is not the problem.
Hosting company reports everything working as intended, as evidenced by the site loads for everyone else. (Points finger at office, I agree)
Internet connection (Cox) ruled out, as other traffic flows.
Internet gateway ruled out by powers above me (Im betting the problem is there but need ammo).
