I have a customer with 2 distant offices, each connected to internet via its own ADSL dialup, and having VPN tunnel inbetween.
Office 1 has IP range 192.168.1.1/24
Office 2 has IP range 192.168.2.1/24
On each side there is D-link DFL-210 firewall/router, having permanent VPN established.
Now, all years everything worked OK, no problems, until last friday when DFL-210 in Office 1 died.
We replaced this router with the same model, and reconfigured it to match the old configuration.
Now, everything is working OK, EXCEPT main shared printer. It is printing randomly, for example:
- if user XY prints to this shared printer, sometimes it prints OK, but sometimes it prints to random printer on other location in Office 2!!!
- sometimes it prints only 1 page out of many, but sometimes it prints many copies of single page
Printer is HP LaserJet M1319F Multi Function Device, with fax. It was working normally until we replaced DFL-210.
But it is NOT NETWORK printer - it is installed locally via USB on server, and all is connected to local GigaBit SWITCH.
The only thing that is in common with replaced D-link is network GATEWAY address, which is IP address of replaced d-link DFL-210.
Any idea, if there is some IP rule or something, that needs to be present for shared printing to work?
