I have ESX Server in subnet B (192.168.10.0) and I have AD & DNS Server in Subnet A (192.168.0.0)
I have that
[root@localhost:~] esxcli network ip route ipv4 list
Network Netmask Gateway Interface Source
------------ ------------- ------------ --------- ------
default 0.0.0.0 192.168.10.1 vmk0 MANUAL
192.168.0.0 255.255.255.0 192.168.10.0 vmk0 MANUAL
192.168.10.0 255.255.255.0 0.0.0.0 vmk0 MANUAL
What will do to get connect from Subnet A to Subnet B ?

If you want routing between two subnets you have to introduce a router... I assume you added a manual route: 192.168.0.0 255.255.255.0 192.168.10.0 vmk0 MANUAL. But this route points to the IP address of the vmkernel adapter... This will not work.
192.168.10.1 is your default gateway so this is where traffic destined to 192.168.0.0 will go to... This must be a router...
Hi Thanks for answer
Sorry, I don´t understand
It´s that I will change ?

What is the command, to fix that

Your host is in subnet A (192.168.10.0/24). All network traffic destined for another subnet must go to your default gateway first. In your case the default gateway is 192.168.10.1. I don't know where the entry 192.168.0.0 255.255.255.0 192.168.10.0 vmk0 MANUAL came from but it is telling your host that traffic for subnet 192.168.0.0 must go to 192.168.10.0 and that will not work... This is basic networking theory and not a specific ESXi issue...
Hi
welcome to the community
This is not an issue for the ESXi and vmkernel ports. You should make the related routing access between these two subnets, So you need to consider if there is an network device like router between these subnets to provide routing via two interfaces as the default gateway of each subnet, you must have access from server A to server B, if you configured their default gateway (DNS is not necessary) correctly in the TCP/IP stack configuration on configuration>networking tab.
