Re: [Vyatta-users] Newbie question about routing

[Sergio Garcia]

Hi again.
Are you sure that the origin address of that "echo reply" is 10.20.20.2 ?

What I mean is that you must have 172.10.5.155 as gateway in your 
172.10.0.100 PC and 10.20.20.1 in 10.20.20.2 PC. Or at least, have a 
static route in their route tables.


I am annoyed about having an request request but having a time out in 
ping command.


Good luck.

Hi Sergio.

Thanks for the reply. I investigated a bit. I got a PC on 172.10.0.0  
(172.10.0.100and I tried to ping 10.20.20.2. At the same time I ran 
WireShark (packet sniffer) on 172.10.0.100: I see the "echo request" 
and also an "echo reply" from 10.20.20.2, but the ping still says 
"request timed out"I don't have any firewall on this pc.


Thanks,

Hi Denha.
Check route table and gateway address of your 172.10.0.0/21 machines.
I'm sure they don't know about how to reply packets to 10.20.20.0/24
addresses.

Try it!

[Vyatta-users] DHCP relay in vif interfaces (vc3)

[Sergio Garcia]

Hi all.
I hope you can help me with this doubt :)
I want to relay dhcp requests incoming from tree eth1 vif's to a dhcp
server but Vyatta VC3 only allows me to select "ethX" interfaces (X goes
from 0 to 23).

Is it possible to do this? Launching dhcrelay manually is not a good
solution, but if it is the only way I will accept.

Thanks in advance

[Vyatta-users] Integrating Vyatta DHCP server with bind

[Sergio Garcia]

Hi all!
I'm new in Vyatta, and I have 3 vifs with DHCP assigning differents 
prefixs-domains and fixed leases.

Now, I want to integrate a DNS server with this DHCP's server... is it 
possible to install bind9 and make it work with DHCP so I only have to 
create the fixed-lease and expect DNS to work?

Thanks in advance,
Sergio
