Subject: [gentoo-user] [OT] NFS through a firewall
Date: Fri, 11 Apr 2008 14:15:47

1 Hello,
2
3 I'm trying to configure the firewall on a client to allow that client
4 to mount an nfs directory. The client runs a netfilter firewall, the
5 server uses tcpwrapper.
6
7 rpcinfo -p on the server shows:

29 100005 3 udp 32767 mountd
30 100005 3 tcp 32767 mountd
31
32 When I try to mount the exported directory when the firewall is
33 running I get a timeout:
34
35 minnie ~ $ mount -v Help/
36 mount: trying 134.153.37.5 prog 100003 vers 3 prot tcp port 2049
37 mount: trying 134.153.37.5 prog 100005 vers 3 prot udp port 32767
38 mount: mount to NFS server 'beryl.esd.mun.ca' failed: timed out
39 (retrying).
40
41 If I drop the client firewall the mount succeeds.
42
43 Can someone help me figure out what must be put in my iptables script
44 to get this to work?
45
46 Thanks,
47 Roger
