Static Routing between Lan Vlan OpenVPN
-
@darwood said in Static Routing between Lan Vlan OpenVPN:
Lan clients traffic for 10.20.1.100 follows the route to 10.0.0.13 gateway.
If this is the gateway what is the cider notation being used here?
-
I wasn't as clear as I could have been.
10.0.0.13 is the IP assigned to the other router by pfsense. The other router has it's own fiber connection. This router is acting as a gateway to 10.20.1.101 The ip range on the note is 10.20.1.0/24, but as far as I can tell only three ip's have ever been in use. 10.20.1.101~103
The Lan clients can ping 10.20.1.101~3 correctly.
Lan is defined as 10.0.0.0/24 GW is 10.0.0.254
Lan and Vlan30 have the same rules in the same order.
For testing:
I set a rule on Vlan30, top of the list : Action Pass, Interface Vlan30, IPV4, Protocol Any, source Any, Destination Address 10.20.1.102, and under advanced, GW is LINK_SER which is defined as 10.0.0.13 under /system/routing/gateways.Using pfsense ping, and host 10.20.1.102, source set to Lan, Ping is successful
Using pfsense ping and host 10.20.1.102, source set to Vlan30, Ping fails.Using pfsense ping and host set to another lan client 10.0.0.14 (random machine), source set to Vlan30, Ping is successful.
BUT
Using pfsense ping and host set to 10.0.0.13. source set to Lan, Ping is successful
however
Using pfsense ping and host set to 10.0.0.13 source set to Vlan30, Ping fails.Vlan30 won't follow the static route setup in /system/routing/static routes. So it doesn't know when I want to ping 10.20.1.102 to use LINK_SER gateway(which is router at 10.0.0.13)
It also seems that Vlan30 can't ping that device, even though it can ping other lan clients on the same subnet.
-
@darwood what about floating rule as it’s essentially on the same interface??
Better yet just creat a NAT rule for that traffic with destinations out that other interface… -
I have tried adding a NAT rule under outbound. Tried with VLAN30 and LAN as the NAT Address.
But this did not work. Ping to other machines on LAN from VLAN30 works, but Ping to 10.20.1.102 fails from VLAN30. Also ping to 10.0.0.13 also fails from VLAN30, but from LAN works.
I should be able to ping 10.0.0.13 from Vlan30 as I can ping other clients on LAN, but this is not the case.
What would allow a ping to clients on LAN from VLAN30, but would block a ping from VLAN30 to that client, but if the ping comes from LAN it works.

Same results ping successful from LAN, fails from VLAN30(it fails from anything other than LAN). Ping from Vlan30 to other LAN machines are successful.

@darwood said in Static Routing between Lan Vlan OpenVPN:
I have identical rules in vlan30, basically allow all. Vlan30 clients can ping lan clients. But Vlan30 clients can not ping 10.20.1.100, and traffic does not reach the LINK_SER gateway.
Sure? Have you sniff the traffic to prove this?
I have tried adding a NAT rule under outbound. Tried with VLAN30 and LAN as the NAT Address.
Can you post a screenshot?

I am remote to this pfsense router atm. But I can ssh in to the pfsense.

This is not helpful. We already know, what is working and what doesn't.Run
pfctl -snto check out the NAT rules.

So I cannot find a proper outbound NAT rule.My assumption is that the gateway only allows access from your LAN subnet. If that's the case you need a rule for masquerading the traffic from VLAN 30 with the LAN address.
It should look like this:
interface: LAN
source: VLAN 30 subnet
destination:10.20.1.0/24
translation: interface address (=LAN address) -
@viragomann would it need to be floating? It’s on the same interface or no??

@JonathanLee
As I understood, the gateway is connected to LAN. LAN subnet can access the remote devices, but VLAN 30 cannot.So if he masquerade VLAN 30 traffic destined to the remote network with the LAN address it should work.
This is done with an outbound NAT rule. -
You are correct, the solution was to create a outbound nat. I had tried this before but I made a mistake for the interface I selected VLAN30, but this was not the correct interface. The interface should have been LAN. Your solution pointed out that mistake.
Thank you.
