VPN IPPool issue
2021-11-04 19:11:50

Under the LAN setup, I have the DHCP server setup with the starting address starting  from 10.1.10.10 to 10.1.10.100 subnet mask for 255.255.255.0

I am trying to set up the VPN IP Pool in preference starting from 10.1.10.150 to 10.1.10.160.

 

It keeps telling me that " The VPN IP pool conflicts with the IP addresses of the LAN. Enter the IP range that will not cause overlap with that of the LAN."

 

Any idea what is going on

@caveboy 10.1.10.150---10.1.10.160 and your LAN IP are in the same network segment, which causes this problem. You can change the VPN IP Pool to 10.1.20.150--10.1.20.160 to fix the issue.

What should I put in the remote subnet field? My IP range at home is 192.168.1.0 mask is 255.255.255.0. My office network starts at  10.1.10.0 with a mask of 255.255.255.0 What should I put in there as the IP number? What does the /means after the IP number? Thank You from a Newbie

Trying to sort out something similar now and I'm looking up CIDR notation.

 

https://www.ionos.com/digitalguide/server/know-how/cidr-classless-inter-domain-routing/

 

Your 10.1.10.10 network with a subnet mask of 255.255.255.0 encompasses addresses 10.1.10.1 to 10.1.10.255. 10.1.10.10 is inside this.

 

This is expressed in CIDR notation as: 10.1.10.1/24.

 

Your VPN IP pool is 10.1.10.150 - 10.1.10.160. This is inside 10.1.10.1/24 and Omada will not allow this due to possible conflicts.

 

The smallest VPN IP pool you can use is a /29 which encompasses 8 addresses according to the link I posted. If you want more than this you can go all the way up to a /24, but you cannot use anything that overlaps with your LAN pool.

 

May I suggest a VPN pool of 10.1.11.1/29?
