Kev, can you post or mail "ifconfig igb0" output for me?


Thanks,

There's still a number of offloading stuff enabled on the parent:

<VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,WOL_MAGIC,VLAN_HWFILTER,VLAN_HWTSO,NOMAP>

Normally it should apply on its own after enabling VLANSpoof, saving and hitting apply configuration. If not we can try manually. Let me know.

I still have this set want me to switch it to disable

[franco]

Worth a try, yes please.

[nivek1612]

Done still

no IP but now the interface looks like this

igb0: flags=8863<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
   description: VLANSpoof
   options=4802028<VLAN_MTU,JUMBO_MTU,WOL_MAGIC,NOMAP>
   ether 00:0e:c4:d2:a4:f9
   media: Ethernet autoselect (1000baseT <full-duplex>)
   status: active
   nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>


and the VLAN that connects to the ISP

igb0_vlan832: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
   description: WAN
   options=4000000<NOMAP>

It's strange that it's stuck with "inet 0.0.0.0 netmask 0xff000000 broadcast 255.255.255.255". Wouldn't that mean dhclient already received an offer? Maybe the request isn't making it to the ISP?

Do we have a packet capture to look at?


Cheers,
Franco

[nivek1612]

Sure any particular setting you want in here

[franco]

capture on vlanspoof with promisc, count not sure I just need the dhcp sequence... might be 100, might be 1000

send via mail


Thanks,
Franco

[nemric]

Yes I always have the pcap I've done when it fails.

I have changed my mac, Manufacturer_xx:xx:xx (xx:xx:xx:xx:xx:xx), the requested IP : Requested IP Address (123.123.123.123) and the hostname : hostname

you won't believe this. turned on capture. re saved WAN. now its shows an IP address but gateway monitor claims the interface is down. Still want the capture

[nivek1612]

tried a reboot now i have this next to WAN .... at a loss now

[franco]

Yes, capture please

[franco]

nemric: in your case the discover is never answered. have you had your VLAN parent assigned and enabled? it looks like the outgoing package is never received by the other end.

[nivek1612]

@franco Just emailed capture
