SG250 FW 2.4 VLAN Management

[GuM Support]

Hello, we have a new SG250-26 with Firmware      2.4.5.71. We want manage the device with VLAN20, IP 10.66.60.137 . In VLAN settings we have add VLAN20, in IP-Configuration- IPv4-Interface we have added IP-Adress 10.66.60.137 with VLAN20, (also is a IP-Adress in VLAN1 aktiv). On (Trunk-) Port24 is the VLAN20 tagged and access to Core-Switch,

We can ping the device from our LAN to the VLAN20-IP-adress but we can not attach over Http, https or SSH.

What can be wrong ? Thanks for help

you will see an option to enable telnet or ssh under TCP/UDP services.

Please mark it as helpful if it resolves your query.

SSH and telent are activated, this works in VLAN1 bur not in VLAN20

Hello,

check the TCP Service Table (page 296 of the attached guide), does the 'Local IP Address' match the IP address of your VLAN 20 interface ?
