SRX

We have aSRX100 at a remote office, we can get to it via the public IP, and the VPN tunnel. On SRX port fe-0/0/1.0 goes to EX port ge-0/0/11, we cannot ping or telnet to the EX2200.

ANy help is apprecioated.

Hi,

From which source are you unable to reach the EX switch in your network ? From you SRX and / or your vpn connection ?

Can you also share the configuration of the EX device.

MarcTB,

I wonder if it is the vlan ID that could be the issue.

Here is the EX2200 config

No should be OK. I cant see an issue with the config. Can you ping from the SRX to the EX? i.e. 192.168.202.1 to 192.168.202.10.

Telnet to the SRX, and ping 192.168.202.10

the result is 7 packets transmitted, 0 packets received.

All the clients on the EX are able to perform their normal daily tasks.

The printers are working.

Just cannot telnet or https to it.

  vlan {
        unit 0 {
            family inet {
                address 102.168.202.10/24;

Typo at the IP address?

Correct, **bleep**......

Saw that last night, will wait for the bundle to come back, and fix it.

Fat fingers kill us hu ?

Thanks

Great  you solved it 🙂 kudo's

EX missing default route?
