[Users] OpenSER + SEMS + Nat?

Hello, I currently have an openser server running on port 5060, and a second that handles voicemail / stateful transaction stuff on port 5070. So, I am having proxy A forward to proxy B to do the handling which are both on the same server, although there seems to be a problem with NAT'ing, when I call 'voicemail' or something I can not hear anything. It seems to be because it is sending the RTP data to the wrong location? It should be sending it back to public-ip-addr-1 when it is sending to an internal ip address 192.168.1.* Here is the log from sems: 101 44811:1466724767 <sip:public-ip-addr-1:5060;nat=yes;ftag=dd9bbf561d35ee06o0;lr=onsip:public-ip-addr-1:5060;nat=yes;ftag=dd9bbf561d35ee06o0;lr=on P-MsgFlags: 0 UA: Linksys/PAP2-3.1.9(LSa) P-Email-Address: test(a)test.com . v=0 o=- 9200357 9200357 IN IP4 192.168.1.241 s=- c=IN IP4 192.168.1.241 t=0 0 m=audio 16420 RTP/AVP 0 2 4 8 18 96 97 98 100 101 a=rtpmap:0 PCMU/8000 a=rtpmap:2 G726-32/8000 a=rtpmap:4 G723/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:18 G729a/8000 a=rtpmap:96 G726-40/8000 a=rtpmap:97 G726-24/8000 a=rtpmap:98 G726-16/8000 a=rtpmap:100 NSE/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 a=ptime:30 a=sendrecv (7856) DEBUG: execute (AmInterfaceHandler.cpp:99): req.method = <INVITE(7856) DEBUG: execute (AmInterfaceHandler.cpp:100): req.user = <115(7856) DEBUG: execute (AmInterfaceHandler.cpp:101): req.domain = <public-ip-addr-1(7856) DEBUG: execute (AmInterfaceHandler.cpp:102): req.dstip = <public-ip-addr-1(7856) DEBUG: execute (AmInterfaceHandler.cpp:103): req.port = <5070(7856) DEBUG: execute (AmInterfaceHandler.cpp:104): req.r_uri = < sip:115@public-ip-addr-1:5070(7856) DEBUG: execute (AmInterfaceHandler.cpp:105): req.from_uri = < sip:1000@192.168.1.241:5060(7856) DEBUG: execute (AmInterfaceHandler.cpp:106): req.from = <Brandon1 < sip:1000@test.mydomain.com>(7856) DEBUG: execute (AmInterfaceHandler.cpp:107): req.to = << sip:115@test.mydomain.com>(7856) DEBUG: execute (AmInterfaceHandler.cpp:108): req.callid = < 81e2d596-978fccc6(a)192.168.1.241(7856) DEBUG: execute (AmInterfaceHandler.cpp:109): req.from_tag = <dd9bbf561d35ee06o0(7856) DEBUG: execute (AmInterfaceHandler.cpp:110): req.to_tag = <(7856) DEBUG: execute (AmInterfaceHandler.cpp:113): cseq_str = <101(7856) DEBUG: execute (AmInterfaceHandler.cpp:119): cseq = <101>(101) (7856) DEBUG: execute (AmInterfaceHandler.cpp:121): req.key = <44811:1466724767(7856) DEBUG: execute (AmInterfaceHandler.cpp:122): req.route = <<sip:public-ip-addr-1:5060;nat=yes;ftag=dd9bbf561d35ee06o0;lr=on>(7856) DEBUG: execute (AmInterfaceHandler.cpp:123): req.next_hop = <sip:public-ip-addr-1:5060;nat=yes;ftag=dd9bbf561d35ee06o0;lr=on(7856) DEBUG: execute (AmInterfaceHandler.cpp:128): hdrs = <P-MsgFlags: 0 UA: Linksys/PAP2-3.1.9(LSa) P-Email-Address: test(a)test.com (7856) DEBUG: execute (AmInterfaceHandler.cpp:133): body = <v=0 o=- 9200357 9200357 IN IP4 192.168.1.241 s=- c=IN IP4 192.168.1.241 t=0 0 m=audio 16420 RTP/AVP 0 2 4 8 18 96 97 98 100 101 a=rtpmap:0 PCMU/8000 a=rtpmap:2 G726-32/8000 a=rtpmap:4 G723/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:18 G729a/8000 a=rtpmap:96 G726-40/8000 a=rtpmap:97 G726-24/8000 a=rtpmap:98 G726-16/8000 a=rtpmap:100 NSE/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 a=ptime:30 a=sendrecv (7856) DEBUG: execute (AmInterfaceHandler.cpp:144): Request OK: dispatch it!
