I am affected by this bug also. Basically, no matter what you do, Force Rport always shows "Auto (No)". 
In certain business scenarios you need not to have peers, but all the options should be global.

The issue, it seems, is that "nat=yes" is deprecated, but it works. But there is no other way to get a global signaling that would produce
Symmetric RTP:          Yes
Force rport:            Yes

Any other option for "nat=" shows as "Auto (no)"

> I noticed that it was impossible to set nat=force_rport in the general section of sip.conf. It actually has no effect when issuing cli command "sip show settings" (result is Force rport: Auto (No).
> The function to reload configurations in chan_sip.c sets the flag SIP_PAGE3_NAT_AUTO_RPORT in the global flags and the function sip_parse_nat_option in config_parser.c will only add the flag SIP_NAT_FORCE_RPORT if SIP_PAGE3_NAT_AUTO_RPORT is not present.
> So, it seems impossible to raise the flag SIP_NAT_FORCE_RPORT in the [general] section of sip.conf.
