I recently upgraded my 3com NBX to software R6_5_22 and I have lost web access from outside addressing. If I am on the local VLAN I can get into the web. With upgrading, does this block a port? any help would be greatly appreciated.
Don't believe any ports were blocked in any of the newer releases. I would check to verify your IP has not changed, the default gateway is still correct and/or the firewall port forwarding has not changed.
