We have one Peplink Balance 380, HW version 1, firmware 6.2.2.
On this B380 we have 2 WAN connections from 2 different suppliers using different technologies (fiber and cable), both with fixed IP address.
Behind this B380 we do have one Microsoft Server 2008 with Microsoft Exchange working as Mail Server. This is working fine, however for remote access we do use the embeded Outlook Web Access (OWA) with a self signed https.
The main issue is that this is working just fine with the fix IP address of one of the suppliers (Cable), but not with the other supplier (Fiber).
We already performed several tests with the supplier, including setting the if IP address in a PC connected directly in the router of the supplier and using Wireshark we are able to see the requests for port 443 reaching to wireshark. This should mean that the https trafic is crossing the supplier’s router and should be reaching B380, but from there it doesn’t reach the OWA…
I already checked and recheacked the inbound roules and I can’t find the reason why this is happening. Both inbound roules for both WAn are exactly configured the same way, and so, if it is working OK for one WAN, it should also be working the same way for the second WAN, but it is not…
Thank you Very Much
