No, reflexive ACLs do not "reflect" for local traffic. You would need
to use PBR to hairpin the local traffic to an interface so it looks like
transit traffic to the router. I know I have seen this discussed in the
past...check the archives for an sample config. :)

Subject: really quick yes or no, reflective access-lists

Hi

Just a quick one, Can someone tell me if reflective access-lists effect
traffic from the local router as normal? I thought they did but

ip access-list extended inbound

 permit ospf any any

 permit icmp any any

 evaluate reflect

ip access-list extended outbound

 permit icmp any any

 permit tcp any any reflect reflect

 permit udp any any reflect reflect

interface Serial0

ip access-group inbound in

ip access-group outbound out

int fa0

ip address 1.1.1.1 255.255.255.0

telnet 150.1.2.2 /sour fa0 fail when the inbound and outbound are
configured.

Telnets from the switch to 150.1.2.2 on the same subnet using a static
route pointing to 1.1.1.1 work fine.

Any thoughts please?

Thanks in advance

Alex
