21.7 Legacy Series / How to check WAN IP lease time?

« on: September 28, 2021, 03:15:50 pm »

Hello,

I have VDSL Modem in Bridge mode and my Opnsense router is attached to that. How can I check my WAN IP lease time from Opnsense?

d4 is an undefined option and 7d is 'Vendor Identifying Vendor Specific or as Huawei puts it 'Vendor-identifying vendor-specific information option, used only by a DHCP server to send enterprise number information to a client.' dhclient doesn't use them but flags them in the logs, you can safely ignore the entries.

Thanks for the information good sir.

Hello,

My infrastructure is

Zyxel VDSL-router in bridge mode -> Shuttle ds77u (opnsense) -> unifi 8port 60W switch -> Unifi nano HD connected directly to 8 port switch & Unifi Flex mini 4port switch connected directly to 8 pot switch for my PC.

I'm using many VLANs. DHCP is off in unifi 8port switch. For every 10 minutes inn Opnsense general logs I see

2021-03-01T17:54:24   dhclient[53615]   bound to MyWANIPaddress -- renewal in 600 seconds.   
2021-03-01T17:54:24   dhclient[64424]   Creating resolv.conf   
2021-03-01T17:54:24   dhclient[53615]   unknown dhcp option value 0xd4   
2021-03-01T17:54:24   dhclient[53615]   unknown dhcp option value 0x7d

I wonder what this is and how to stop it?

21.1 Legacy Series / Re: Local connections dropped at seemingly random intervals

« on: February 19, 2021, 09:21:57 am »

After upgrading to 21.1 I lose LAN connection to the router after 10-15 minutes so I had to downgrade to 20.1. My network

VDSL-router in bridge mode -> shuttle ds77u (opnsense) -> uqibuiti switch -> PC

But when I connected

VDSL-router in bridge mode -> shuttle ds77u (opnsense) -> PC

it still dropped connection to Shuttle after 10-15min to shuttle. First dropped WAN connection and few minutes after that LAN-connection. So I cannot update to 21.1 even if i wanted to

Hello,

My idea is to use UDM as a managed switch/unifi controller/wireless access point and firewall/dhcp and everything else would be managed on Shuttle Opnsense. Is this even possible or do I need "plain" unifi managed switch + unifi network controller on a raspberry pi etc.

Hello,

I switched unifi LAN to 192.168.2.1 and Opnsense box to 192.168.6.1. Now I have Double-NAT situation which I don't want

Tracing route to google.com [172.217.21.142]
over a maximum of 30 hops:

  1    <1 ms    <1 ms    <1 ms  unifi.localdomain [192.168.2.1]
  2    <1 ms    <1 ms    <1 ms  192.168.6.1
  3    12 ms    12 ms    11 ms  dsl-nnnnn []

Is this because I have now connected Opnsense box to WAN port of UDM? Should I just switch to LAN port then so Opnsense could do firewall stuff?

Not quite what I was looking for for that does double NAT

Hello,

What i'm missing here? I'm using shuttle ds77u as Opnsense box and Unifi Dream machine + USW Mini switch.

Topology: VDSL-modem in bridged mode -> Opnsense -> UDM -> Unifi USW Flex mini -> desktop

Networks on Opnsense and UDM

• LAN 192.168.3.0/24
• WAN
• VLAN10 10.10.10.0/24

IP addresses

• VDSL-bridge 192.168.1.1
• Shuttle/Opnsense box IP 192.168.3.1 (set by opnsense LAN settings)
• UDM IP 192.168.3.2 (set by UDM in its LAN settings)
• USW flex mini IP 192.168.3.10 (given by ?? maybe UDM DHCP since when I set it to static lease on opnsense it says offline)

UDM doesn't show up at all in in DHCP leases on Opnsense, USW flex mini does on the LAN interface.

• When I connect my desktop to USW flex mini "all/trunk" port meaning network 192.168.3.0/24 I can access 192.168.3.1 and UDM controller on 192.168.3.2 just fine but I don't have any internet connectivity.
• When I connect my desktop to USW flex mini port configured as "vlan10" meaning network 10.10.10.0/24 I can access 192.168.3.1 but not 192.168.3.2 but I have internet connection.

Questions:
A) Why cannot I access 192.168.3.2 from the 10.10.10.0/24 VLAN network?
B) Why I don't have internet access on 192.168.3.0/24 LAN network?
C) Why doesn't Opnsense give IP to UDM?
