Title: DFL-800 add vlan
Post by: yoteur on February 25, 2010, 09:20:56 AM

Hi all!

I try to configure the wan3(dmz) of my DFL 800 with a new IP in VLAN.
WAN1 and WAN2 are configured without VLAN.

I add a vlan on WAN3/DMZ with an ID an IP a network and a gateway.
The interface ethernet WAN3/DMZ is configured with the same IP network an GW as the VLAN.

I had some rules allow rules in order to allow traffic from interface LAN to VLAN and to interface ethernet.

After that unable to ping the address given to the interface ethernet WAN3/DMZ and VLAN.
Moreover I can see that in logging:

Warning     ARP
00300049    Default_Access_Rule       wan3_124
   172.16.2.12
   
   invalid_arp_sender_ip_address
drop
rev=1 hwsender=00-50-56-bd-6c-5b hwdest=ff-ff-ff-ff-ff-ff arp=request srcenet=00-50-56-bd-6c-5b

Could you help me?
Thanks

A VLAN would not use the same network ID as the interface itself, that will cause issues.

Thanks for your reply.
What do you call network ID? The IP adress?
thanks!

Ok understand!

I have changed the IP of my WAN3 to an ip and network different from the VLAN ip and network and it works great.
Thanks.
