with ospf routing do i enable masquerade rule as im moving off a bridge type setup?

i have got the ip addresse sorted out already on the interfaces jus nee to know about this rule

If you are using private IP's then yes of course you need masquerade rules, but make sure that OSPF traffic is not masqueraded.

ok thant explanes my Problem


so i must add somthing like this


chain=srcnat action=masquerade protocol=!ospf out-interface=internal-BtoI
