<![CDATA[Cannot continue to ping & access to CARP IP]]>Dear all,

I'm getting a problem. It is "Cannot continue to ping & access to CARP IP" . I have 2 PF boxes in the cluster topology. I have also 2 internet connections with 2 CARP IP separate.

  • The CARP IP on 1st line is working well
  • But the other one on 2nd line only work in 15 minutes if I perform to modify on CARP setting. After 15 minutes, it doesn't work again

I would like to public some services (HTTP, SMTP, POP3, …) on this CARP IP to the internet.

Could everybody please show me how to fix this problem? May I need to modify speed and duplex on the interface that has problem?

Thank in advances !
DQM

can you try with just a (dumb)switch as WAN2?

You probably need to explain your setup a bit more. Maybe include a topology diagram?

Attached file is my current topology

Do you have 2 physical lines with the same IP address/range? How does the routing work?

I have 2 physical lines from 2 ISP separate, the first is lease line & the other is FTTH (see the topology for detailed information)

From where to where are you testing?

I have tested from internet

Do you have CARP working on the LAN?

The LAN CARP IP & the WAN CARP IP01 are working well. The WAN CARP IP02 only work in 15 minutes if I perfom modify some configuration (delete & re-create, change to another IP address in the same subnet, duplex, …)

Did everyone get the same my problem? Pls give me your advice !

Thanks in advance,
DQM

You should test this before moving to CARP.
