I have a local server. Specs below

Distributor ID: Ubuntu
Description:    Ubuntu 22.04.5 LTS
Release:    22.04
Codename:   jammy

I had set up the NFS file system, and it worked for months. However, I just realized I failed to enable the UFW firewall. I did so, and these are the current rules of UFW

sudo ufw status verbose
Status: active
Logging: on (low)
Default: deny (incoming), allow (outgoing), disabled (routed)
New profiles: skip

2049                       ALLOW IN    192.168.5.249

22/tcp                     ALLOW IN    192.168.5.0/24

111                        ALLOW IN    192.168.5.0/24

Unfortunately, I can no longer connect to my NFS server, and I cannot figure out why. If I disable the UFW firewall, I can connect again, so I know the issue is with the firewall. Can anybody help please?
