Issue
RHEL server cannot mount NFS share through firewall after reboot. The firewall allows NFS through the following ports:
- TCP and UDP 111 for sunrpc
- TCP 2049 (nfsd-tcp)
- UDP 2049 (nfsd)
- RPC 100005 (mountd)
- RPC 100003 (nfsprog)
- RPC 100021 (nlockmgr)
- RPC 150001 (pcnfsd)
After the reboot the RHEL server started using port 1234 when trying to mount the NFS share and fails.
