Access Web Server (port 80, port 443) in LAN over VPN

I've successfully got a VPN server running in my office so I can VPN in from my Macbook using TunnelBlick. The VPN tunnels to the 10.0.4.0 subnet which is a server management LAN that I've recently created.

I'm now trying to manage some boxes remotely using HP ILO. One of my servers has a static IP of 10.0.4.21. If I ping it whilst connected to the VPN, the ping responds without any problems:

PING 10.0.4.21 (10.0.4.21): 56 data bytes
64 bytes from 10.0.4.21: icmp_seq=0 ttl=63 time=40.979 ms

6 packets transmitted, 6 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 31.610/36.120/41.242/3.869 ms

However, when I hit the IP in a web browser, the request times out so I can't access the ILO web dashboard at all. I can access these pages whilst being physically connected to the LAN though.

Under my OpenVPN interface firewall rules, I've configured the following rules:

I'm not sure if these rules are correct, but seen as I have many servers, I want to configure a rule which says "access to port 80 or port 443 on any server is okay, as long as it's in the 10.0.4.0 subnet if you're connected through a VPN tunnel."

What else should I try to get this working? I'm quite new to pfsense so there are still quite a few network routing techniques that I'm not an expert of and would like a push in the right direction if possible.

Thanks in advance for any help!
