XGS1930 change management VLAN

nielsscheldeman

I have a setup with 4 XGS1930-52HP switches and 3 GS1900-8HP switches. I want to move them to a separate management VLAN. Created VLAN11 and moved the GS1900 switches to that management VLAN. Created a rule on firewall so that 1 of my servervm's can access that VLAN. Works fine for the GS1900's

But If I add IP-Address with VLAN ID and change default gateway on XGS1930 I'm unable to access the switch from my VM on the new IP. If I set my VM in VLAN11 it works fine. Because the GS1900 series work fine I don't think it's firewall policy problem, but routing problem.

However if I ping from the other network to the switch's new IP it works fine and also telnet 443 works fine.

Hi @nielsscheldeman

This appears to be a triangular/asymmetric route. May I know if your XGS1930 is still having the original VLAN and IP address? If so, this could be a case of the triangular/asymmetric route. Please try to remove the original VLAN's IP address first. Or, configuring SNAT rules on the firewall.

Yes original IP is still there, I'm doing this remote and wanted to be sure that I'm not shutting myself out…
