I realise there is lots of similar threads but as far as I can tell our config is setup 'correctly' to enable inter vlan routing.
What we are trying to achieve is gain internet access from our old subnet 10.120.140.0/22 to our new router 10.120.136.1, I've created a vlan (136) with the IP 10.120.136.2 and ip-helper of our dhcp in the other subnet; we were using the default vlan for the other subnet as we were using dynamic LACP, whilst troubleshooting i've tried to create another vlan but this has not helped!
I can ping the gateways of either vlan within either vlan so I think routing is working? However if I point the machine to the gateway in the 140.0/22 subnet I have no access.
I also don't get a DHCP response from the 136 vlan so that functionality isn't working either.
Any ideas what is going on here? Ignore the somewhat messy vlans as I can't move some of our LACP uplinks yet as the dynamic LACP keeps them in vlan 1.
I realise this switch isn't great on the routing front but I believe it should do this! I'm off to check on firmware now which is almost certainly not the latest, will check back soon.
