No connectivity on direct RJ45 connection


My ISP provides internet by using RJ45 lan cable.

Problem is if I dont connect the router and connect the RJ45 cable directly to the motherboard's RJ45 female there is no connectivity. None of the LEDs glow.

If I use my router the LEDs on the LAN ports start glowing and I have full connectivity.

I am using OpenBSD 6.3.

Can someone explain this to me ?

EDIT: Ubuntu worked fine with a direct connection.

Not an openBSD user but off the top of my head, is BSD set up to pull an IP using DHCP? How was ubuntu set up? Your ISP isn't assigning you a static IP unless you paid for one so it is going to most likely be dynamic.

Let me explain my situation.

My ISP has given me a static local IP

172.16.197.XXX #IP Address
255.255.255.0 #subnet mask
172.16.197.1 #Default gateway
8.8.8.8 #DNS1
8.8.4.4 #DNS2

During the installation process OpenBSD lets you set a static IP but the problem is with the cable directly connected to the motherboard there is no connectivity.
The LEDs on the lan adapter doesn't glow.

Gateway issue? With the router in place, the router is your gateway, without it, the ISP should have a gateway - is it "172.16.197.1"?

Well, just thought about it - that's not going to NOT give you connectivity - the lan light should still be active...

Does the ubuntu install have the same IP Since it works with ubuntu and not bsd?

Sorry, odd problem...

Yes 17.16.197.1 is the gateway. I configured the above IP configuration in Ubuntu and it worked fine.

It may sound strange but I think using Pfsense on this box for a period of time must have partially damaged the onboard NIC.

How is your hostname.if(5) for the interface configured?

https://man.openbsd.org/hostname.if

I have added another NIC to my system.

I want to set static IP on it. Please guide me through the process.

Code:
$ ifconfig                                                                 
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 32768
        index 3 priority 0 llprio 3
        groups: lo
        inet6 ::1 prefixlen 128
        inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3
        inet 127.0.0.1 netmask 0xff000000
re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        lladdr 60:45:cb:87:53:a5
        index 1 priority 0 llprio 3
        groups: egress
        media: Ethernet autoselect (100baseTX full-duplex,rxpause,txpause)
        status: active
        inet 192.168.0.100 netmask 0xffffff00 broadcast 192.168.0.255
enc0: flags=0<>
        index 2 priority 0 llprio 3
        groups: enc
        status: active
udav0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
        lladdr 00:e0:4c:53:44:58
        index 4 priority 0 llprio 3
        media: Ethernet none
pflog0: flags=141<UP,RUNNING,PROMISC> mtu 33136
        index 5 priority 0 llprio 3
        groups: pflog
udav0 is the interface I want to set static IP on. Please help.

I started using Linux in 2007 and I find it easy now but OpenBSD is something totally new to me.

I don't want to tweak the system to a point where it breaks. I dont have a clonezilla backup.

Budget is tight atm and cant invest on a new external HDD.
