Synology NAS loses connection after IPS is enabled in LAN to WAN Rule ?

Hi,

I'm struggling to understand an issue I'm facing. It seems like my NAS is losing few functionalities once I activate IPS (lantowan_general) in my LAN to WAN rule.

I see some IP being blocked, unable to perform cloud sync, etc.. but it's not clear why ?

In general, how can I find out why the IPS is blocking/preventing some traffic from happening ?

Thanks,
N

I'm starting to think the problem has nothing to do with Sophos but rather with my NAS itself. I'll try to investigate something down this road first before bothering you any further. I really appreciate…

DS220+. Can that have any impact ?

No, it shouldn't, it's a current model. I have a DS918+ and DS1019+ running for 3+ years behind an XG106 or XG125w.

I've now found out that it is not the NAS that is the issue. Any docker pull xx I do from any host fails.

Downloading an ISO, seems to work.

Strangely, on one of my linux box, when I forced the MTU to a different value, it would then successfully download.

But I'm not sure which MTU I should be using, and how to set it across my network ?
