Overlapping Proxy ID"s

L1 Bithead

I have a IPSEC site to site VPN with a Check Point firewall.  In the Palo Alto I have networks / proxy ID's that overlap each other?  Can this cause issues?

 

For example I have:

 

Local                                                   Remote

192.168.50.0/24                         10.241.8.0/24

192.168.50.0/24                         10.241.0.0/16

 

Because 10.241.8.0 /24 is included in 10.241.0.0/16 is something like this know to cause problems?

are these both to the same Checkpoint?

if so, both ends can (should) delete the proxyID with the 10.241.8.0/24 subnet as this serves no purpose

 

it shouldn't cause any issues, but why risk it (if one end decides the /24 has precedence and the other prefers the /16, traffic could potentially get discarded)
