PFsense Connection suddenly stops when downloading files..

[Randolf]

Good day,

This problem suddenly occur and I don't know why because my pfsense configuration is all default .

WAN config
interface : wan
address: ipv4
protocol: any
source: any
destination: 192.168.0.10

LAN config

interface : wan
address: ipv4
protocol: any
source: any
destination: any

What should I do to stop this connection timeout in LAN?
