Host remoto não acessível pela LAN, mas acessível pela WAN

Estou em uma rede local que se comunica com a web por meio de um roteador / firewall pfSense. Eu tenho dois servidores remotos do Debian, onde eu deveria poder acessar as portas 22 (SSH), 80 (HTTP), 8080 (HTTP) e 443 (HTTPS).

Meu problema é:

de fora da LAN (mesmo com o mesmo computador usando conexão telefônica 4G ou TOR ou VPN primeiro), posso acessar os dois servidores remotos (PING, Telnet, SSH, navegador, ...)
de dentro da LAN (qualquer computador), eu posso alcançar um deles, mas não o outro

O que tentei até agora:

traceroute mostra o mesmo lúpulo
no servidor inacessível, eu desabilitei ufw e fail2ban , e limpei todos os riles em iptable
no pfSense, não há regra específica
Eu uso tcpdump e telnet para testar a conectividade: nada aparece quando tento da LAN
nmap de dentro da LAN:

# nmap aaa.aaa.aaa

Starting Nmap 6.47 ( http://nmap.org ) at 2016-03-17 10:28 CET
Nmap scan report for aaa.aaa.aaa (X.X.X.X)
Host is up (0.00024s latency).
Not shown: 996 closed ports
PORT     STATE SERVICE
22/tcp   open  ssh
80/tcp   open  http
443/tcp  open  https
8080/tcp open  http-proxy

Nmap done: 1 IP address (1 host up) scanned in 2.48 seconds

nmap da LAN externa (ou através de VPN ou TOR):

# nmap aaa.aaa.aaa -Pn

Starting Nmap 6.47 ( http://nmap.org ) at 2016-03-17 10:43 CET
Nmap scan report for aaa.aaa.aaa (X.X.X.X)
Host is up (0.00020s latency).
All 1000 scanned ports on aaa.aaa.aaa (X.X.X.X) are filtered

Nmap done: 1 IP address (1 host up) scanned in 26.08 seconds

EDIT: aqui está o resultado do pcap no pfSense

Estou executando o pcap no pfSense: pfsense.aaa.aaa/diag_packet_capture.php, capturando tudo no IP X.X.X.X. Aqui está o que eu recebo:

na interface WAN: nada
na interface da LAN:

Como isso pode ser? O que mais eu posso tentar?

Meu palpite é que há algum bloqueio de firewall entre minha LAN e meu servidor (pfSense ou no servidor), mas como posso resolver isso?

Agradecemos antecipadamente pela sua ajuda e apoio muito apreciados.

OK, o pfSense foi mal configurado. Havia uma regra no Firewall para a interface LAN, fazendo com que tudo passasse pelo IP do meu servidor remoto ...

Solução: desative a rota no pfSense > Firewall > Regras > LAN.
