Voip 1720, One Way Voice

duh_s

hi
available in such a working diagram:
voip gateway ap1005 (wan port with a real ip) - router fbr-4000 (wan port with a real ip) - voip gateway ap700 (wan port to local ip)

voip gateway ap1005 Mapped 4 telephone line via a router fbr-4000 to another voip gateway ap700
spelled out in the router only 2 rules nat (virtul server):

tcp 1720 на wan_ap700
udp 23000-24999 на wan_ap700

ap700 registered in the only route: 0.0.0.0/0.0.0.0 lan_fbr-4000

instead need fbr-4000 put pfsense

respectively ap700 change route: 0.0.0.0/0.0.0.0 lan_pfsense

and create pfsense

firewall - nat - Port Forward

WAN_provider1 TCP * * WAN_provider1 net 1720 wan_ap700 1720
WAN_provider1 UDP * * WAN_RESURS net 23000 - 24999 wan_ap700 23000 - 24999

and two additional rules

IPv4 TCP LAN net * * 1720 *
IPv4 UDP LAN net * * 23000 - 24999 *

BUT, if calling from the ap700 ap1005 on a connection is made, but heard only by what they say ap700 by ap1005, and vice versa - can not be heard

One Way Voice: ap700 -> ap1005 but ap1005 X->X ap700
