Dell Switch – VLAN Routing Configuration

I'm dealing with a S4048T-ON switch.

It has 3 vlans. One for the workstations, one for management of servers etc and one for actuall usage of those server.

VLAN 226 is the first one and everything is fine. I'm dealing with VLAN 227 on which I have no internet access and I cant's resolve external ips, but I can ping and resolve local hosts from 226. That the problem. We need internet connectivity on VLAN 227 aswell.

The switch has been configured by someone before me, so I have to catch up.

Here is the output of the ip show route command:

*S    0.0.0.0/0          via 192.168.26.1, Vl 226                                        
                         via 192.168.27.1, Vl 227
 C    192.168.26.0/24    Direct, Vl 226                                                  
 C    192.168.27.0/24    Direct, Vl 227                                                  

Router NAT config:

target     prot opt source               destination
SNAT       all  --  192.168.26.0/24     !192.168.0.0/16       to:XXXXXXXXX
SNAT       all  --  192.168.29.0/24     !192.168.0.0/16       to:XXXXXXXXX
MASQUERADE  all  --  anywhere             anywhere

This is the running config of the switch at the moment
