Strange routes to University in Japan?

[deanfourie]

Hey guys! So I have a question regarding some really strange routes in my routing table.

I recently put my Huawei B818 4G router into bridged mode behind pfSense, which is now my main router. Upon doing so, I notice these static entries that pop in and out of my routing table. They are

163.47.0.1 - acoresw05.metro-cit.ac.jp
163.47.0.2 - aedgesw30.metro-cit.ac.jp
163.47.0.3 - doesn't resolve.

And also I am noticing a route for 163.47.0.0/16.

Now, given that I am routing traffic through a university in Japan, this did strike me as a bit odd.



Your thoughts?

Thanks

Looking at your routing table - you have manually added the two static router for metro-cit.ac.jp

If you didn't add them - I would suggest that you update/change the password, as someone is adding those routes - one is a gateway route (acoresw05), and the other is a host...

Thanks for the reply. Ok but I cannot delete them. It says that they cannot be deleted.

Also there is nothing in my static routes. I think these routes may be being pushed down from the ISP

Plus they are on my WAN interface which is receiving IP via DHCP from ISP

You appear to be using a 4G/LTE router. Are you geographically close to Japan? Is it simply because your mobile operator routes their traffic through Japan?
