Previous and SLiRP

So I have this working according to instructions and I can even telnet back to the host on 42323.  My question is... do I have to rebuild from source to use the other 5 re-direct slots?

Ideally I'd swap out 42323 with 42322 for SSH, port 80, 443, 25, and maybe one other.

I can't seem to figure out even from a glance at the source where the slirp.conf stuff is.

https://sourceforge.net/p/previous/code/HEAD/tree/trunk/src/enet_slirp.c

It's in enet_slirp_start


void enet_slirp_start(Uint8 *mac) {
   struct in_addr guest_addr;
   
   if (!slirp_inited) {
       Log_Printf(LOG_WARN, "Initializing SLIRP");
       slirp_inited=1;
       slirp_init();
       inet_aton("10.0.2.15", &guest_addr);
       slirp_redir(0, 42323, guest_addr, 23);
   }
   if (slirp_inited && !slirp_started) {
       Log_Printf(LOG_WARN, "Starting SLIRP");
       slirp_started=1;
       slirpq = QueueCreate();
       slirp_mutex=SDL_CreateMutex();
       tick_func_handle=SDL_CreateThread(tick_func,"SLiRPTickThread", (void *)NULL);
   }
}


Specifically this line:


slirp_redir(0, 42323, guest_addr, 23);
