I am facing an issue when trying to accomplish something i assumed was fairly simple.
I am configuring a VPS cluster for Containers and Virtual Machines with Proxmox.
The scenario is the following:
4 Servers sharing the 18.104.22.168/29 network. Each host is assigned an IP on this range.
22.214.171.124/26 as a "Secondary Address" on this vlan.
I have deployed a Windows server 2012 Virtual Machine acting as the DHCP Server for the VM's.
The idea is to configure the Containers and Virtual Machines to obtain IP's via DHCP.
Here is the thing, all the servers are on the same vlan, no ACL is configured other than to allow such mentioned subnets. The issue is this.
If both, the DHCP Server is on the same server as the VM Client, then the dhcp request/offer takes place without issues.
If the VM client is on a different Server, even though they are on the same vlan, nothing happens.
Im trying to think what could be the issue as it seems like its a networking issue.
Is the EtherChannel in Access mode or trunk mode? If it is in access mode then try with portfast.
Here is my config.
SVI on L3 Switch
description CUSTOM VLAN PROXMOX CLOUD
ip address 126.96.36.199 255.255.255.192 secondary
ip address 10.99.99.1 255.255.255.0 secondary
ip address 188.8.131.52 255.255.255.248
no ip redirects
ip route-cache same-interface
ipv6 address 2A03:9A60:F5::1/48
Then, the config on the Distribution Switches
SRV1C1S1#sho run int gi1/0/34
Current configuration : 201 bytes
switchport access vlan 3807
switchport mode access
ip access-group INTERNALDEFENSE in
If I assign any IP of the 184.108.40.206/26 network to any VM on any container, it works just fine.
Its DHCP the issue at the moment, not sure why though.
As it turns out, the issue was the **bleep** ACL.
I removed it just to test and it works as expected now. I will look into it and see why its blocking it.
Thanks for the time.
You mentioned about no acl.
