LAN <-> LAN VPN/routing help

[andrewrMember]

Hi,

I currently using two ZeroShell boxes to create a LAN < -> LAN VPN, I can get the VPN tunnel connected, how ever I’m sturggling to route traffic through it.

I’ve got the network setup as follows:

Subnet 1

---

SERVER 1 <

---

> ZEROSHELL 1 <

---

> ADSL 1

SERVER 1 – 192.168.1.100

ZEROSHELL LOCAL (ETH00) – 192.168.1.1
ZEROSHELL WAN (ETH01) – 192.168.7.101
ZEROSHELL VPN00 – 192.168.254.1

ADSL 1 – 192.168.7.1

Subnet 2

---

SERVER 2 <

---

> ZEROSHELL 2 <

---

> ADSL 2

SERVER 2 – 192.168.2.100

ZEROSHELL LOCAL (ETH00) – 192.168.2.1
ZEROSHELL WAN (ETH01) – 192.168.7.102
ZEROSHELL VPN00 – 192.168.254.2

ADSL ROUTER – 192.168.7.2

I’ve tried numerous entries in the routing table, all going out of VPN00 but i’m still struggling to get it route traffic through the VPN tunnel.

Any advice?

Thanks,

Andrew

This is fairly simple to do.

On Zeroshell 1 create the following Static Route:
Destination: 192.168.2.0
Netmask: 255.255.255.0
Type: Gateway
Gateway: 192.168.254.2
Metric: 0

And on Zeroshell 2:

Destination: 192.168.1.0
Netmask: 255.255.255.0
Type: Gateway
Gateway: 192.168.254.1
Metric: 0

On ZeroShell 1 that works.

On ZeroShell 2 I get an error:
Apr 04 15:41,11 ERROR: Static route 192.168.1.0/255.255.255.0 via 192.168.254.1 metric 0 not added: RTNETLINK answers: No such proces…

EDIT: Figured it out, there was no entry for 192.168.254.0 in the routing table on ZeroShell 2, added it and it works brilliantly.

Thank you!
