Thanks Tim for your help. DNS : this a DNS that is configured to be used by LAN1 (instead of the one that is advertised by the ISP). I reverted to 7.1.0. No issues. With this version, I noticed that DNS is reported as 192.168.21.1 which is what is set in the interface (see herebelow). On the other hand, as you noticed with 7.4.1 DNS is reported as 103.86.96.100 while it is set to 192.168.21.1 in the interface (I reverted to 7.4.1 to double check this). There is cleary a different behaviour. Really strange. Could it be the reason of the problem I reported?
Please find here below the startup file for 7.1.0
