Issue with routing table and CT

[micfrip]

Hi,

I have have a really weird issue with one of my server.

Currently I rent two physical servers at OVH. Both are using Proxmox (standard installation).

However, one CT is running perfectly on the first server (S1) but not on the second physical server (S2): it seems that the routing table becomes incorrect when i move the CT from S1 to S2.

Here is the route -n result on S1:

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
XXX.XX.XXX.254 0.0.0.0 255.255.255.255 UH 0 0 0 eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 1003 0 0 eth0
0.0.0.0 XXX.XX.XXX.254 0.0.0.0 UG 0 0 0 eth0

which is correct

On S2:

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
XXX.XX.XXX.254 0.0.0.0 255.255.255.255 UH 0 0 0 eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 1003 0 0 eth0
0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 eth0

the red line is not correct.
If I delete and add the right values manually with "route del -net x.x.x.x netmask y.y.y.y", it works but when the servers restarts, the previous values are back !

From my point of view it seems that a value coming from S2 is overwriting the CT's values... but I don't know which ones.

Any help would be appreciated.

Kind regards,


Michaël
