Regra Iptables

bom dia

tenho 2 firewall um em cada unidade, matriz e filial, quero acessa um servidor na filial via terminal server, mas não estou conseguindo, pingo normal para o servidor que quero acessar. já liberei a porta do terminal 3389.

firewall matriz: 172.12.10.1
firewall filial: 172.12.14.1
servidor no qual quero acessar: 172.16.14.100

obs: pingo normalmente para o servidor que quero acessar mas não consigo acesar via TS.

Como vc liberou essas regras? Poste-as aki.

-A FORWARD -p tcp --dport 3389 -j ACCEPT

tenho outro firewall e estou acessando normalmente somente esse que não acesso o servidor via ts

Kra, vc deve por todas as suas regras aki pra gente saber. Liste tb as q já estão implementadas:

# iptables -nL
# iptables -t nat -nL

Uai, o OUTPUT tá com a política DROP. Nesse caso, vc teria q autorizar a saída dele tb...

Olá emerson, você está utilizando vpn? Se sim, qual procotolo?

Bom Dia ,

Seu Firewall esta com muitas regras repetidas, como esta abaixo que libera OUTPUT para qualquer ip.

ACCEPT all -- 0.0.0.0/0 0.0.0.0/0
ACCEPT all -- 0.0.0.0/0 0.0.0.0/0
ACCEPT all -- 0.0.0.0/0 0.0.0.0/0

De uma revisada neste firewall seu e confira depois se realmente o TS esta ativo no servidor, se o firewall do próprio servidor não esta bloqueando a porta 3389.

segue abaixo minhas regras da Matriz iptables:
