Trouble with getting to a synology nas internally after switch isp
Hi there,
Today I've switched from ISP. I use the Deco in router mode. It is configured as DMZ host in the router of my old ISP. I run a synology NAS at home, which is accessible from the inside of the network as well as on the outside. This worked fine with my old ISP.
Today I switched to a new ISP, also made the same configuration. Unfortunately reaching the destination on the 'external hostaddress' internally wasn't possible. Externally everything ran fine.
Configuration is as folllows:
ROUTER - DECO M9 - NAS
The router makes DHCP leases in the 192.168.1.xxx series. The Deco M9 is set to 192.168.68.xxx. Of course the Deco M9 has a static DHCP lease on the router, and is set as DMZ host.
After getting a tip from another forum I started looking at 'NAT loopback' and found several topics on this forum handling this problem. I've tried the following points;
1. Disabling Trendmicro security
2. Setting the QOS settings to standard
3. Emptying the high priority list in deco.
Note: it was working on my previous ISP, with the same configuration (of course the router of the ISP is different).
To rule out whether it is a problem of the router of my ISP, I connected the Synology directly to the router of the ISP. And all of a sudden the synology was reachable from within my own network (even a client on the Deco M9 wireless network).
How can I get this back working with the Deco M9?
Thanks in advance!
