Title: Question to 19.7.2 release notes: fix writing gateway information for DNS
Post by: hbc on August 06, 2019, 03:16:54 pm

Hello,

in 19.7.2 there was this hint:

Code: [Select]

system: fix writing gateway information for DNS servers
I hoped this would solve my problem with icmp redirects, but instead of just one dns added to gateway list, all dns are now added to gateway list.
For the dns server in far subnets routed anyway via gateway this will not be a problem, but why add a gateway entry for a dns server in the same layer 2 subnet? Instead of sending direct on link/wire, the dns requests are sent to the local router and it returns icmp redirect messages, since the packet could/should go directly.

After every reboot, I have to delete this host route.

Could you please fix this and stop creating host routes for dns servers on the same subnet as a direct attached interface?

Thanks.
