As my nodes experience some problems keeping connections up, I would like to ask for the proper network settings. My setup so far is:
1 Server node:
RPi 4 / 4GB (Performance ~44MB/s) NAT-Router FRITZ!Box 7360, 1 Port forwarded TCP/2XXXX to Pi, DynDNS (server always reachable per SSH, 2XXXX always open from outside)
2 Client nodes running Windows 10 64-bit 1 Client node running Android 9
Client nodes behind NAT-Router FRITZ!Box 7240 at different location, UPnP activated, DynDNS (another pi behind this router is always reachable), or over mobile internet. Connection issues are affecting all 3 clients but syncing of ~4GB was successful - when connection was up.
On both routers IPv6 dual stack activated, both DynDNS IPv6 dual stack
On the server node following settings were applied:
Listening address: tcp://:2XXXX NAT-Traversal: no Global Announce enable: no Local Announce enable: no
Following settings were applied to clients:
NAT-Traversal: yes Global Announce enabled: yes Local Announce ensbled: no
External device (server node) address: tcp://(DynDNS-URL of server):2XXXX
Are this the intended settings for the described setup? Are there other settings that are relevant for connectivity?
