Reply To: Query regarding DHCP Hi all, So recently, I’ve noticed that when I have my server on, some mobile apps on my phone wont load. Anyone else had this at all? The only change…

Most likely DNS related as above mentioned by @Grisu.

Have not read of any recent DNS issues with ASUS kit but worth a try updating to Version 3.0.0.4.386.49599 as they have added since Version 3.0.0.4.386.46061:

Added 3rd party DNS server list in WAN –> DNS to help users enhance the connection security.

Also;

1. Any switches in network ?
2. Also check manually assigned IP address is outside routers DHCP IP pool.
3. Check DNS settings on mobile phone to see if there are any clues (DNS server home).
4. Are router and server on same Subnet (sounds like they are) ?

I cannot decide if this maybe NAT issue, but worth a thought.

TBH – it may well be worth introducing a second router/switch so that your server environment is on a different subnet from Wifi / Internet router (general use) etc. or maybe even provide an airgap solution between the two IP networks ?

P.S. Draytek kit is great for this
