R600 SSH across L3 failure

[philip_francis1]

Hello, I can SSH in to this R600 access point when my laptop is connected to the same VLAN but unable to SSH from another VLAN.
This would normally mean a default gateway problem, however I confirm the default gateway of the access point is correct and I can still ping the access point from other VLANs so I cannot understand what is wrong here.
Does anyone have any ideas ?
