I have a Cisco ASA setup with two interfaces:
inside: 192.168.2.254 / 255.255.255.0 SecLevel:100
outside: 192.168.3.250 / 255.255.255.0 SecLevel: 0
I have a static route setup to allow PCs on the inside network to access the internet via a gateway on the outside interface (3.254):
outside 0.0.0.0 0.0.0.0 192.168.3.254
This all works fine.
I now need to be able to access a PC on the outside interface (3.253) from a PC on the inside interface on port 35300. I understand I should be able to do this with no problems, as I'm going from a higher security level to a lower one. However I can't get any connection.
Do I need to set up a seperate static route? Perhaps the route above is overriding what I need to be able to do (is it routing ALL traffic through the gateway?)
Any advice on how to do this would be apprecaited.
I am configuring this via ASDM but the config can be seen as below:
