[nos-bbs] Jnos networking problem

[Jerome Schatten]

Miguel...

I have been down this road too (only with cable rather than dsl).

I concluded that only if you're using port forwarding do you need the 
static routing. If you're not using port forwarding, then put the jnos 
lan address of tun0 into the DMZ and it should just work.

You will need to protect yourself against intruders by using 'tcp access 
permit' statements in autoexec.nos

I have never had a problem with the system configured in this manner. 
You can see the bad guys sending syn packets trying to get in, but they 
can't get passed the 'tcp access' if they're not on the list.

Best,
