Uplink to another switch using single LAN interface? DNS problem?
-
Install Pfsense on a HDD with dual Intel NICs (wan=em0 lan=em1). From em1, I connect to my main #1 switch (DGS-1224T VLAN & trunking & mirror capable…but not configured) Problem is with switch #2 POE (Netgear POE GS-108PE) ....SAME subnet, uplinked to switch #1 via straight CAT6,
The devices on switch #2 connect to Internet.... but I cannot see or access them from devices on switch #1 and only some appear in the pfsense DHCP lease table.
Any ideas on what may be configured wrong?
Could this be a DNS related?Misc. Settings ( I think OK.....
• Pfsense for DHCP on LAN 192.168.1.100 thru .200 ( although most devices given static IP within 192.168.1.2 thru .99)
• WAN interface set as DHCP client (with DYNDNS set-up)
• RIPv2 & SNMP "on" all devices.
• Added (snort, squid, darkstat, etc)
• Port forwarding (avermedia cameras)
• DNS forwarding??should be set to?????Misc....
HW MB form factor negates option of adding another NIC as PFsense interface (em2)... I read this might solve the problem.
I have two gigabit managed switches:
1- Dlink DGS-1224T (VLAN &Trunking Capable...but not configured...connected to LAN (em1)
2- Netgear POE (GS-108PE for cameras)....SAME subnet, uplink to main switch (DGS-1224)Waiting for Book: Pfsense: definitive reference (2-3 week backorder amazon)

Could this be a DNS related?Yes, it could be DNS related. How are you trying to access these devices? - by hostname or by IP address? What response do you see when you try both access methods?
The devices which don't appear in the pfSense DHCP table might not be there because they used a different DHCP server OR their old DHCP lease hadn't expired when you looked.

What can you see from switch two? Of those machines on switch 2 that get IP addresses from pfSense, what can they see/do? Can they ping the firewall's LAN interface?
Also what IP addresses are the switches themselves on? They both appear to be managed switches so will have IP addresses themselves. This means switch 2 may also have a DHCP server running (you'd need to turn that off). You may also have switch #2 on an IP address already in use on the network.
