Sonicwalls have a setting that allow a /24 subnet being natted to a different /24 subnet to get mapped on a one to one basis.
Example, 192.168.1.10 will get bidirectionally natted to 10.0.0.10, 192.168.1.11 will get bidirectionally natted to 10.0.0.11, etc...
The last octet will always stay the same which allows one nat rule to be added so both sides can initiate connections. Is there a way to do this on the Palo without doing a static one to one nat for each mapping?
dynamic NAT does this also, but only for one subnet to another subnet, not for a bunch of random subnets based on the last octet only
ie: dynamic nat 192.168.0.3/24 will translate to 10.0.0.3/24
are there overlapping IP addresses?
if both sides of the tunnel do dynamic nat, this would work
if there's no overlap you'd just need a policy in each direction that applies dynamic source nat
could you sketch the environment?
