IOS 11.3 and policy routing breaks NFS


I have put a route map for a transparent http proxy on two Cat 5509s. Works fine. Unfortunately it breaks NFS altough NFS should not go through the Acls.

IOS is 11.3(6)WA4(9).

Route map looks like this:

route-map proxination permit 10

match ip address 110

set ip next-hop

And the acl 110:

access-list 110 deny tcp any eq www

access-list 110 permit tcp any any eq www

access-list 110 deny tcp any any

When i bind this to the int vlan #, then various nfs links do not work anymore, some do.

Strange isn't it? Anybody any idea?

Thx in advance

Re: IOS 11.3 and policy routing breaks NFS

route-map proxination permit 20

set ip next-hop default

Not sure of the exact syntax of the set line (doing this from memory), but you need to tell the route map what to do with the packets which don't match access list 110 (or other preceeding routemaps). There are other ways to do the same job, just make sure you pick one which does not force the router into process switching (check the command reference for your IOS release).

Good luck and have fun!
