Model : Archer C7

Hardware Version : Not Clear

Firmware Version :

ISP : Ziggo.nl

Goodday,

First of all, I’m very happy with the Archer C7 Router. After installation our WIFI network at home is very fast.

Our ISP Ziggo.nl change the mode in them router to Bridge.

We are now a problem with the email. The email off mine pop3 account will not transfer anymore to outlook or mine synology NAS, it stays at the server and will not transfer.

I’ve contact also Synology to discuss this problem, they says: We’ve checked the domain address and seems there are some problems with the Reverse DNS. I’ve discussed this problem with mine ISP (Ziggo.nl), but they says our router is just a pass-through device.

All the important ports of the NAS are Forward in the Archer.

I’ve also disabled the firewall option in the Archer, but no solution.

What could it be: Can someone help me with this problem
