I have several FreeBSD clients connecting to a FreeBSD NFS server via a private gigabit LAN for backup purposes. Both clients and server has IPFW with all traffic between clients and server allowed on the private LAN. All clients and the server were running 5.3-RELEASE-p10 with IPFW, and NFS was working just fine. Then I upgraded all clients to 5.4-RELEASE-p1 and the NFS was working fine. Finally I upgraded the NFS server to 5.4-RELEASE-p1 and now NFS has stopped working. The clients experience RPC timeouts: RPCPROG_NFS: RPC: Port mapper failure - RPC: Timed out My NFS server rc.conf has the following as per manual: nfs_server_enable="YES" rpcbind_enable="YES" mountd_flags="-r" Clients have: nfs_client_enable="YES" IPFW rules amount to: allow all from NFS_SERVER to NFS_CLIENT in via INTERNAL_IF allow all from NFS_CLIENT to NFS_SERVER out via INTERNAL_IF and appear at the top of the ruleset. I even added nfs_reserved_port_only="YES" nfs_server_flags="-u -t -n 4 -h " to the server but it makes no difference. /etc/hosts and /etc/hosts.allow are also configured correctly (re: NFS was working with 5.3-RELEASE-p10). Obviously something has changed in the NFS system under 5.4, but I have no clue where to look. Any help is greatly appreciated.
