[SR-Users] siptrace source ip causes martians

Hi, i have a kamailio instance, which is connected to two subnets (A and B) and exchanges sip messages between them. I have setup the siptrace module to send hep tracing messages of all sip messages to a host in subnet B. This works really well for sip messages arriving on the IP of subnet B - for those arriving on subnet A however it doesnt work. The hep messages have the interface address of subnet A set as source address. Since the machine receiving the HEP messages also is connected to both subnet A and B, these messages are (correctly) rejected as martians and never reach the sipcapture module on that host. this is on kamailio 3.3.4. Is there a way to force the source IP of outgoing HEP messages in the siptrace module? thanks kind regards Thilo
