1 Wan in DHCP and multiple CARP on LAN
-
Hi all,
I want to make this configuration (mono Wan) :–------pfsense1 (FW1)----------------- (lan + opt2(vlan20) + opt3 (vlan21) + 2 others vlan)
| |
WAN (dhcp) --------------- pfsync-opt1
| |
| |
--------pfsense2 (FW2)----------------- (lan + opt2(vlan20) + opt3 (vlan21) + 2 others vlan) (same as FW1)Carp is configured on all the LAn and vlan.
How can I do to make the dhclient stopping on FW1 and starting on FW2 in case of outage on FW1 ? Is it possible to do it like this ?
I think I have a solution in configuring the Wan interface as Fixe IP with a fake ip that I take from the /24 range that is given to me
(ex : My fixe wan ip send by my provider is : 12.23.34.56/24, I put the ip 12.23.34.1/24 on wan FW1 and 12.23.34.2/24 on FW2 and carp 12.23.34.56/24.)
What's your feeling about that ? I would prefer a release/renew of the Wan ip while switching from a FW to another if possible !2nd question : Can we put weight on the carp interface ? For exemple, I only want to switch if I loose WAN interface or Lan interface but not the other vlan.
3rd Question : is it possible to have some interface master and the other backup on the same FW ? If yes, how does the flow pass through the FW ? (via the pfsync interface ?).thanks for your help.
