SME Server 10 - cannot reach Internet [RESOLVED]
« on: March 14, 2022, 03:14:25 PM »
Hello,

I have a fresh installation of SME Server 10, on Dell PowerEdge T40 server with 2 NIC (internal + added TP Link external card).

The server is installed as Server + Gateway with Gateway address aa.bb.cc.146.

I have used SME config tool to configure the server.

Here is the output of ip addr:
Code: [Select]
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
2: dummy0: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN group default qlen 1000
    link/ether 10:00:01:02:03:04 brd ff:ff:ff:ff:ff:ff
3: enp3s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN group default qlen 1000
    link/ether bc:0f:9a:9a:31:df brd ff:ff:ff:ff:ff:ff
    inet aa.bb.cc.146/29 brd aa.bb.cc.151 scope global enp3s0
       valid_lft forever preferred_lft forever
4: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether a4:bb:6d:61:26:a3 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.1/21 brd 192.168.7.255 scope global eno1
       valid_lft forever preferred_lft forever


And here is the output of ip route and route -n commands:

Code: [Select]
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         aa.bb.cc.145    0.0.0.0         UG    0      0        0 enp3s0
aa.bb.cc.144    0.0.0.0         255.255.255.248 U     0      0        0 enp3s0
aa.bb.cc.145    0.0.0.0         255.255.255.255 UH    0      0        0 enp3s0
192.168.0.0     0.0.0.0         255.255.248.0   U     0      0        0 eno1



default via aa.bb.cc.145 dev enp3s0
aa.bb.cc.144/29 dev enp3s0 proto kernel scope link src aa.bb.cc.146
aa.bb.cc.145 dev enp3s0 scope link
192.168.0.0/21 dev eno1 proto kernel scope link src 192.168.1.1

The issue is that computers connected to internal network (or the server itself) cannot reach internet.

I see that state of the enp3so interface is down. If I try to use
Code: [Select]
ifup command the output is:


Code: [Select]
RTNETLINK answers: File exists
And interface stays in DOWN state.

Any clue/help is greatly appreciated.

Best regards,
Milan

A clean install, no restored backup? They are not the same thing.

Ummmm not sure why your external interface is /29? Single IP is /32 so start with that for simplicity.

I guess the TP link is the external enp3s0 ?

Not sure why you have dummy there.

Go to the CLI admin and reconfigure your networking again and let us know the stages & options.
...
1. Read the Manual
2. Read the Wiki
3. Don't ask for support on Unsupported versions of software
4. I have a job, wife, and kids and do this in my spare time. If you want something fixed, please help.

added TP Link external card

Hi, it is a cheap pci D-Link card, right (regarding the first three mac address blocks) ?
I have same issue some years ago with this brand, if you can try an Intel pci-e card or other brand.

Is the card seen in uefi ? I think no because it is to old (or you have to play with "legacy" options to enable it)

It seems that issue has been caused by the Network card.
The PCI-e replacement worked.

Thank you both for the responses,
