Hi, I have a sip gateway connect to the LAN side of RV180 router which has ALG enabled. I have no problem to make and receive calls but sometime I see the router does not forward the 'Bye' message from the VOIP service provider to the sip gateway. Attached a wireshark capture on both WAN and LAN of RV180. sip gateway ip: 192.168.30.100 RV180 WAN ip: 22.214.171.124 VOIP provider ip: 126.96.36.199 and 188.8.131.52 In the capture frame 4292, a 'Bye' message reaches the WAN of RV180 but it never forward the 'Bye' to the sip gateway with internal ip All settings in RV180 are default with only ALG enabled. I tried to setup Access Rule or Port Forward but none seems to work. Not sure if they are over-ruled by ALG? With ALG enabled, is it possible to have individual Access Rule? If there are conflicts between ALG and Access Rule, which has higer priority?
