Accessing the external ip through the internal ip.

[Alexandre11]

Customer has an internal nat ip 10.130.32.117 and external ip 177.124.177.69 and wants to access from inside the vpn 10.130.32.117 through external ip 177.124.177.69 on port 1826
He gets the error below:

Last login: Mon Jul 18 13:33:55 2022 from 10.100.0.43
[support@test100-dondomenico ~]$ telnet 177.124.177.69 1826
Trying 177.124.177.69...
telnet: connect to address 177.124.177.69: Connection timed out

the ip 10.130.32.117 is released in the firewall, that is, with full rules in the outgoing and incoming firewall.

if this is not NAT 1:1 you need PAT 
Inside IP:1826 ->Outside IP:1826
also you need 
ACL apply  IN direction on OUT interface 
permit tcp any  <INside IP> 1826

Yes. I already did this. NAT 1:1 and PAT and I applied ACL IN and ACL OUT, but don't work, Any other soluttion ?
