Currently, MASQUERADE in firewall4 does not support setting snat_port and directly reports an error without creating rules. This modification enables MASQUERADE to support setting snat_port. Signed-off-by: HSXX <513733973@qq.com>

In a NAT444 dynamic IP environment where the ISP's BRAS uses Full-Cone NAT, limiting the MASQUERADE port range on OpenWrt can help prevent the number of sessions on the BRAS side from exceeding the limit. However, currently, if snat_port is configured in OpenWrt's NAT rules, the MASQUERADE rule fails to generate and produces an error. This modification ensures that MASQUERADE rules are correctly generated even when snat_port is specified.
