How to reply to TCP packet on custom port with EtherCard library ???

Hi,
I have Ethernet module ENC28J60 and I am trying to receive TCP packet and reply to it but on the custom port.
I used example from the EtherCard library rbbb_server and on default port 80 it works fine, but I need it to work on custom port 8567.
So I tried with: ether.hisport = 8567 and I managed to receive tcp packet, but reply doesn’t work… So how can I replay to tcp packet on custom port???

#include <EtherCard.h>

// ethernet interface mac address, must be unique on the LAN
static byte mymac[] = { 0x74,0x69,0x69,0x2D,0x30,0x31 };
static byte myip[] = { 192,168,1,203 };

byte Ethernet::buffer[500];
BufferFiller bfill;
 char* data;
 
void setup () {
    Serial.begin(57600);
  Serial.println("\n[backSoon]");
  ether.hisport = 8567;
  if (ether.begin(sizeof Ethernet::buffer, mymac) == 0)
    Serial.println(F("Failed to access Ethernet controller"));
  ether.staticSetup(myip);
}

static word homePage() {
  long t = millis() / 1000;
  word h = t / 3600;
  byte m = (t / 60) % 60;
  byte s = t % 60;
  bfill = ether.tcpOffset();
  bfill.emit_p(PSTR(
    "HTTP/1.0 200 OK\r\n"
    "Content-Type: text/html\r\n"
    "Pragma: no-cache\r\n"
    "\r\n"

      h/10, h%10, m/10, m%10, s/10, s%10);
  return bfill.position();
}

void loop () {
  word len = ether.packetReceive();
  word pos = ether.packetLoop(len);
  
  if (pos)  // check if valid tcp data is received
  {  
  //Receiving tcp works fine
  data = (char *) Ethernet::buffer + pos;
  Serial.print(data);  
  ether.httpServerReply(homePage()); // send web page data
  }
