That makes sense. The odd thing is, a) the problems are still there if I block access to the internet for all machines but the gateway machine b) an IP continues to appear in the logs, even if I block access to it using iptables (and I confirmed that no new connections could be made). > If they aren't IPs connected with the business might be work googling > the IP address, see if the traffic is known about by others, or let us > know details (port, IP, protocol (tcp or udp etc). There's mostly third-party software running on the LAN so a priori everything could be legitimate. > Full output of the SuSE firewall errors might point to something as well. Will look into that. Currently, a factory reset of the router caused it to be unable to reconnect to the internet, so I'll plug in a new router on Monday. Perhaps it is the router after all. Thanks.
