Hi All,
Recently i just install one NethServer for Transparent proxy at our Company.
This NS have 02 interface , one for Internet Access with have default GW , rest one is for Internal access without GW.
Internet <–> (ens224 - Red zone) NethServer (ens192 - Green Zone - 192.168.243.0/28) <–> (192.168.243.1)Cores SW (192.168.237.1) <–> Access SW <–> my PC (192.168.237.115/24)
All others VLans on my network will connect to internet through this NS - PRoxy, static route set on NS for my PC VLan
My issue is i only can ping to the NS (with very high latency) when the Ens224 (internet interface) is up, when this interface down, i cannot ping to NS anymore.
i have some test by removing the default route on interface Ens224, add the default on Interface Ens192, by this way i can ping to NS with normal latency (<1 ms)
i also try to remove Default Gw on both interfaces, adding 0.0.0.0/0 by static route with smaller metric for Ens224 but not success, only one route with destination 0.0.0.0/0 appear, otherwise it will override the old one.
Any advice ?
Thanks a lot,
Van.
