Hi Murali,

Unfortunately, open5gs(nextepc) does not support the range of the ip pool.
As such, it is not possible at this time.

Let me paste the related source code regarding the issue.

Sorry for not being help this.

Best regards,
   Sukchan

In src/pgw/pgw-context.c, pgw_ue_pool_generate(), line 1207

           /* Exclude Network Address */
            if (memcmp(ue_ip->addr, subnet->sub.sub, maxbytes) == 0)
continue;

            /* Exclude Broadcast Address */
            if (memcmp(ue_ip->addr, broadcast, maxbytes) == 0) continue;

            /* Exclude TUN IP Address */
            if (memcmp(ue_ip->addr, subnet->gw.sub, maxbytes) == 0)
continue;
