Dear all good mrg,
I am facing an issue. The issue is always need router restart in my company because outlook error for receive E-mail for all PC'S. So the E-mail server is in another location not in LAN. Here i am unable to find out whats wrong. Because suddenly within 15-16 days the POP3/smtp outlook become receive error for all PC. after the restart of main router this issue become clear and runs smooth for 15 days/some days. So while outlook receive error, the internet works fine.
So whats wrong there?
I have attached my network LAN diagram and the main thing we need to consider:
Main router is not with WIFI.
Router is ruining LEDE firmware(Lynksyn 3200 ACM model)
PFsense has been acting as proxy, nothing blocked in firewall rule.
