CGNAT: If traffic streams/flows are higher say (>4M) PPPoE subscribers are getting timed out
Say there are 180 Flows for 24K Subscribers. With this scenario pppoe sessions gets timed out.
To Reproduce
Version (bngblaster -v):
root@SN-STD-25-421167005:/home/supervisor # bngblaster -v
Version: 0.8.34
Compiler: GNU (9.4.0)
IO Modes: packet_mmap_raw (default), packet_mmap, raw
