SF302-08P layer 3 mode

Hi,

i'm trying to configure SF302-08P in layer 3 mode.

ports 1 to 8 have ip phones and desktops, port GE1 in connected to a router (not cisco) that links to the internet.

i created vlan 100 and assigned to ports 1 to 8 (untagged)

i created vlan 200 and assigned to port ge1 (untagged)

activated dhcp server , created pool with 192.168.26.0/24 gw 192.168.26.1

                       |router A| (192.168.16.0/24 gw 192.168.16.1)

                           |

                           |

                           | GE1 (192.168.16.14)

                       | SF302-08P |

                                 |

                                 |

SPA504G+DESKTOP |    SPA504G+DESKTOP

        192.168.26.2                      192.168.26.4

         192.168.26.3                      192.168.26.5

the problem that i'm facing is that SPA504G and desktops access the internet with their inter address 192.168.26.0/24 and not 192.168.16.14.

is there a way to achieve what i'm looking ? how does routing work in this case ? shouldn't there be some kind of NAT ?

thank you

SF302-08P layer 3 mode

Hello Luis,

Is there a particular reason that the switch needs to be in Layer 3 Mode?

I think your scenario would work better if you configure NAT on your router and let the router act as the DHCP server. Then, the switch could be in Layer 2 Mode.

SF302-08P layer 3 mode

Hi,

i need to use separate vlan for voice/data and provide dhcp .

upstream router is very basic, doesn't support vlan or dhcp options for provisioning.
