cascade connection between SecureNAT and Local Bridge servers

[json-ltl]

Hello,

I am trying to make a cascade connection, but unfortunately, I cannot access the Internet. I have two VPS: the first one uses SecureNAT, and the second one uses Local Bridge. I set up the Local Bridge on VPS_2 with the help of the following link:
http://blog.lincoln.hk/blog/2013/05/17/ ... al-bridge/
On VPS_1, I enabled SecureNAT and set the default gateway to 192.168.7.1, but there is no Internet access through this gateway for the clients on VPS_1.


VPS_1 (SecureNAT) ---> (CASCADE Connection) ---> VPS_2 (Has access to Internet and it has dhcp server on interface tap_soft)

Code: Select all

VPS_2:
	tap_soft: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.7.1  netmask 255.255.255.0  broadcast 192.168.7.255

Simply disable SecureNAT on VPS_1 to make it work.

I need to use the SecureNAT on VPS_1. My question is how can i use SecureNAT while the VPS_2 use the Local Bridge.

No, you don't need it at all, look https://www.vpnusers.com/viewtopic.php? ... 838#p97123
You've only replaced VPS_2 SecureNAT with Linux equivalents and call it a "Local Bridge".

[json-ltl]

so we can't have a connection between SecureNAT and Local Bridge servers!? what IP address should i use for default gateway?

[solo]

Well, you can't have two DHCP servers. You've already set a DG as dhcp-option=tap_soft,3,192.168.7.1 - remember?

[json-ltl]

When I use the SecureNat on both servers, I have access to the Internet. I set the default gateway on both servers to the same IP address using the SecureNat. Now, I wonder why I cannot access the Internet by changing from SecureNat to Local Bridge on VPS_2, as you said they are equivalent.
